I have no chance of spending this kind of money with a 5th child on the way...so you can tell me to fk off and it's cool. I think people have questions as to where did all the money spent on this build go to? With cast pistons I can't imagine the rotating assembly. Clarity is key with a motor. Knowing who built it is nice but it's not a selling point that will get 15k. To be blunt we have a standard bore 455 from a 70 Electra with cast pistons and off the shelf edelbrock heads. I guess it's the salesman coming out in me...and I'm not trying to be rude I'm trying to help you hit your price point believe it or not. Potential buyers want to see cost justification.
absolutely waterbox. It's my fault that i prematurely posted the engine, giving some vague information and specs. Partly because i'm very green to the whole process of engine and car building and also just having been impatient and not waiting until i dug up the build sheet. Which i now have, and because you reminded me, i will post, post haste! Lol! Thank you, i do appreciate the advice and insight. It's not the first time somebody has expressed these concerns regarding my post. My apologies to all, and thank you for everyone's patience, understanding, and advice.
Okay gents here goes, hopefully this will clear the air. First here are all the things that were done by my engine builder, who just so everybody is up to speed, builds some of the sickest race engines coming out of nyc, and did me a personal favor by assembling my motor. These are just the machine shop processes. Parts specs and prices will follow so everyone can understand my math and see that what i am asking for is actually a screaming deal. This was done to a low miles, fastidiously maintained 1970 455 out of my buddy's electra. -boil block -checked for cracks -milled deck surfaces even -bored and honed cylinders with torque plate -installed new cam bearings and freeze plugs -paint block -checked line hone on block -boil crank - cut and polished crank (.010 under) -resize big end of connecting rods -press on new pistons -gap rings -degree cam -check pistons to valve -compute compression ratio here is the internals parts list -speed pro pistons -speed pro rings -speed pro main,rod, and cam bearings -ta performance 212 camshaft -ta 3/8" push rods 9.950 - oil pump pick up tube and screen -cometic head gaskets - felpro intake, oil pan, timing chain, water pump, and valve cover gaskets -arp bolts for everything -rear main seal - 5 qts. Comp cams break in oil the assembly and machine services cost $4500 pistons, gaskets, push rods, camshaft, deep sump pan, ta performance timing cover and oil pump, water pump, ta valve covers cost around $2900 the block cost $1500 (i had to buy the whole car, it was a 4 door, not too many people will view that as a loss) by my math, thats $8,900. -pro systems 850 custom carb $1,000 -edelbrock performer aluminum heads $2,200 -edelbrock performer b4b aluminum intake $380 -march performance serpentine kit $1,900 -hooker long tube headers $600 -msd ignition, distributor, and coil $800 -all the doo dads, thermostat housing,plugs,wires,belts,bolts etc. $400? again by my math that's a grand total of $16,180 not including assembly, minor fabrication of a few brackets and installation labor. That's where i said i have over $20k into the motor. i am also asking $15k, that's negotiable. Also considering what this is... Not a bad deal. This isn't your backyard built or "just some engine builders" built engine as the previous gentleman implied. This motor is no joke. Don't compare it to your motor guys work. Cuz it ain't! i will be posting all of the technical data in a separate reply after this one so that all questions as to what it is will be plain to see. Also the dyno results will be posted in a few more weeks as well. I hope this clears the recurring question of "where is all the money in this?"
Great story,thanks for sharing. You could easily boost the BBB and make more HP you could ever use in a car set up as yours. Since it doesn't currently have forged pistons install new forged pistons with the proper dish to get the compression to around 8.9 to 1, add a girdle and your ready to make 700-900HP ,depending on the size of your 'nads, with 5-10 psi of boost.Will be totally streetable. There are several buick guys doing this. I just built one along these lines for my '71 ,but haven't had the chance to finish the installation before winter. Good luck with the sale. Looking at the pics it looks like no expense was spared. All first class parts,with the exception of pistons, and the surrounding under hood parts are well thought out and installed. Nice car. gary
thanks gary. I've been gettin beat up on here a bit, lol! It's nice to see somebody that can recognize the effort and love that went into this build, by all parties involved. Also thank you for the boosted information. I have all intentions on doing just that, running a pro charger or maybe some small twins after the motor gets the necessary mods. I'm currently heading in the direction of full on race car however at the moment. I'm at the track about a dozen times a year and i will be retiring within a year or two, so i will be spending much, much more time there. So i'm pretty sure i will use the 85' gn as a dedicated race car at this point. It's an 85' so, perfect candidate. Dare i mention this here but, i have an opportunity to acquire a stage v6 block and heads from a good friend and would enjoy ending up putting the heart that was originally intended for this gn, back in! Only with ballz, and sell or save the 455 for a future project. Because with a little green and the good hands of the pros i can pull 1500+ from the v6 and would love to be one of the few in the 7's with that platform. That being said, i obviously just put a lot of cabbage into the 455. I know i can do the mods, fairly easily, on the v8 and run 5-10 lbs. All day and have the car in the 9's. My question i would love to throw at you is. How much power can i "reliably" pull from that block? I know with some stage heads, maybe fuel injection, max out the boost for whatever the block can handle, and a hefty diet on the gbody, i may be able to still go pretty damn quick. No? It is my understanding though that although the stock crank can be made to be pretty stout and handle bigger power, the block however, even girdled and with some magic mojo would probably only be able to handle 1000 to 1200 or so hp safely, reliably, and consistently. Please forgive me if i sound nuts and uneducated. Their both true. Keeping in mind i will stay with the stock chassis, for the moment. I've heard so many different opinions on the subject, but overall i get the impression that without doing an all out aluminum block and forged everything, that the stock 455 block probably isnt the best platform for a big power boosted application. The ceiling is rather small on them. Thank you in advance for any insight.
I'm not using fuel injection, a simple blow-thru carb and procharger with intercooler and meth injection.Looking at probably 775-800hp at 6psi. A similar combo that john Csordas runs turns 9.8 reliably. A couple years ago he pushed the envelope and ran 9.0's at I think 10psi, then in pursuit of a 8 second pass turned the wick up a bit and pushed the crank out near the 1000ft mark. He wasn't girdled though. Anything much more than 800hp with a stock block, even girdled, will make your butt pucker at the stripe.I know some guys made close to 1000 hp, but to race that combo regularly would be questionable.I went very light weight with the rotating assembly and girdled it and filled it.Hopefully I can push it some. With a stock chassis a procharged 455 will make more hp that you'll be able to put to the ground, plus the breakage factor in drive line parts, unless you start beefing everything up in that area.
Thats what I'm going to find out, I'm new to this high tech stuff. So please help me if you can. I'll be asking ???? as I go along. gary
agreed. If done properly, most anything, within reason, can be made to be reliable. Even high horsepower applications. Just like anything else in life that needs attention. If you payed attention to it, it would be fine.
