Does anyone have a copy of their 350 dyno results they can share? My motor is headed to the dyno in a few weeks and I'd like to have something to compare my results to. TIA
Good luck on getting any info on this topic here. I think most of the folks here are ashamed of there small blocks. Getting et's, hp/tq is like pulling teeth on this board. IMO. I have gotten more help with my buick small block on chevy boards, thats a shame.ou:
I don't know anybody who is ashamed about their small block..at least not me...I have not had mine dyno-ed but just had my #'s run on a computer program...if you want that info let me know...:grin:
Not that I'm in any way ashamed of MY 350, :grin: , but I've just never taken the time to find a chassis dyno and run it on one. But I can tell you that it will haul my loaded (tool box, full sized spare, plus whatever junk is sloshing around inside) 4500+ pound LeSabre from 0-60 in under 9 seconds, however much hp that is. Plus, when it's got the Chris-Craft skiboat hooked on the back, it really not aware that it's towing anything. I think that the percieved difference between 455 and 350 input here is more due to more 455 guys doing dyno or track time, and more 350 guys doing street driving. I think.o No: James
Seems like a reasonable explanation... my 350 hasn't been on a dyno or to the track since I bought it 2 years ago. There are a # of guys here that do race their 350 cars. Don't know how many have done dyno time though.
Im new to the forum, and I'm getting scared by the lack of enthusiam for Small Blocks. I just bought a pair of skylarks (71&72) and the one engine that came with them is a small block 350 (stock). I am not well versed in horsepower, but to me, it seems strong, (I can actually squeal tires, which was impossible in my old car, with a dog of a 6 cylinder) but from what I have been reading, It seems the only way to get real power is through big blocks :ball: . I have no intrest in drag racing my car, but I want enough power to hold my own against most cars on the road. I know that aside from supercharging, there is no replacment for displacment, but what are the chances that I can get some power from my small block, without having to sell my kidneys to finance it?
How much power to you want??? There is a way to make the 350 engine put out over 360 hp...without too much trouble...little bigger cam...T/A sp intake..headers..some head work..hotter ign..curve the dist...ect..ect...and the 350 is a lot LIGHTER then the 455...:grin:
There is forced induction as well. You don't have to go crazy with the go fast goodies depending on your goal. After a few flip flops between BBB or BSB and single turbo vs. twin turbos, I've decided to go with a single turbo Buick small block. Why? The main reason is strength. The smallblock does not seem to have the block strength problem the 455 does. To correct those problems would be cost prohibitive as far as I'm concerned. The second reason is weight. While my 69 'Lark won't be a g-machine, I expect it have better handling than the 30+ year old stock suspension can deliver. Even tho the 455 is light by BB standards, it's still heavier than I want. I'm working out details, but have no idea when I can get it done. That little problem of paying for it is an issue at this time.
How much power can it hold? That has yet to be determined. I'm guessing around 500 safely. Beyond that...? This is with good connecting rods of course. I wouldn't be surprised if it could hold more though.
I think the block would be able to hold 700hp. My engine will probably be on the dyno Dec./Jan. to see what it can do and what is the best combination of parts for the most power. Everything that can possibly be done to get the most power is being done to the engine Jim Burek is building. He's estimating it should be around the 475hp range, but it would never hurt to see alittle more:grin: I was thinking down the road of adding a supercharger, like the kit that goes under the hood. There's alot of potential for these engines, it's just investing the money to make them better. With other priorities that are more important in life, I know it's more difficult to achieve. If you go to PAE Enterprises webpage you'll see the Wiseco pistons that'll be going in my engine. I had to wait 6 months for them, but after seeing the quality piston they are I don't mind that I did.
Albert My specs are as follows.. Original block just rebuilt with stock crank..pistons ( 10.25 comp)..heads rebuilt by PAE..J.Burek..3 angle valve job..and new cc valve springs..5/16 adjustable pushrods..J.Burek opened up the heads so that they flow at...246 CFM on the intake side and 168 CFM on the exhaust side...Jim wrote me a little note on the bottom of my flow # sheet..that 246 CFM is capale of making.." 467 HP "... He also supplied me with my cam from Comp Cams..Valve lift..478 intake..500 exhaust..duration at .050..intake 212..exhaust 224... cam installed at 110 intake center line...has a nice little lope...engine also has a T/A sp intake..and T/A headers..and the original q-jet..but has been rebuilt by Al ( GS Thunder )...and has been jetted up some..:laugh: ... We put all these #'s in a computer program ( forgot which one )..and it spit out 367 HP....:TU: ... I have taken the car to Englishtown..and have run a best time of 14.4 at 101 mph....with stock convertor&street tires...14 inch..3.23 posi...stock 350 trans..
My small block Well, I'm not so proud of these numbers but my 350 made 202 HP and 303 ft/lb at the wheels. This was running rich, with a poorly curved ignition system but I was so excited to see a chasis dyno at the track that I jumped at the chance. In a similar state of tune that combo ran 14.8 @ 94. After an introduction to the bottle (100hp shot of nitrous), she ran a 13.8 @ 99. This is all in a 1971 Skylark Convertible with 3.42's. James
Our Buick 350 made about 390HP on the dyno. We have NHRA approved "stock" dished pistons. Our cam lift is stock, .392/.408. Our heads and intake is not ported or polished as per NHRA rules. Our cam does have alot of duration, about .270ish.... Our crank is stroked .013. I do have the dyno sheets, just not with me.... Damn proud of our 350!!!!!!
Current minimum weight for our car, WITH DRIVER!!, is 3470# in J/SA and 3600# in K/SA. Car by itself probably weighs about 3200# with all extra ballast removed.
OK I've been watching this thread for days and finally went to my records and pulled the Dyno Sheet from my 350 that Scotty from PEEGEE performance built about 9 years ago. This engine in a 4040 lb. Skylark with 373 gears and 2800 stall converter runs 13.5's all day at 100 MPH.
