yes, you are right about parts availability. 'somebody did it for you'. you could call it robotic. everything the same. the hunt for 350 parts is always fun. you meet all sorts of people. some good, some bad. i've run 455's, v6's(another project) and the 350. over time i have about 25k in this engine. do i fear blow up, yes, but i would build another. 350's are tough. 7500 is not an issue, some wear always is. have you looked at the ls bottom end and crk shaft location. it looks like a 350 buick. wonder where they got that idea. if i wanted it simple, yeah i would buy chevy. but i don't like it sinple, not my background ben, if we meet, you know i will you tease about putting in a mongrel. no mercy.
I know it’s been a while. The engine build took a little longer than expected. I’ve pulled the Buick 350 and it seems it would be a better idea to part it out for the good stuff. I’ll be posting parts in the for sale section. A few things I will be selling: Doug’s long tube headers SP3 intake MSD distributor MSD ignition box Power master starter Power master alternator TA valve covers TA HD rocker assembly TA timing chain cover with oil pump assembly TA flex plate TA 284 cam and lifters And anything anyone wants off of it…or of course I’ll sell the whole motor. A pic of what came out and what’s going in. Specs on the LS motor for those that care: 5.3 bored over to 5.7, healthy cam, Edelbrock LS1 dual plane intake, flat top pistons, 706 heads (for the high compression) LS3 rods. Dyno results: 436hp on a truck tune. Should be good for 500hp with a proper tune.
That’s correct! The FITech fuel system is going on the LS setup. I put the 4150 carb on the Buick for my own viewing pleasure ☺️
It came in at 387 ft lbs @ 3000 rpm. 427 peak. Again this was an out of the box stock truck tune. A proper tune will really wake it up. I’m pretty sure the 350 wasn’t making that. I would have really liked to dyno the 350 before I tore it apart….just doesn’t make sense to pay for a session though.
It would have been nice to see another 350 on the dyno, not many have been there, with your set up. I now believe the best way to totally hot rod a 350 is to make a very light rotating assembly nice roller cam put on the alum heads and Sp3 and start to spin this thing to 7500. It does not have big piston so use rpm and head velocity to make it rock.
