350 rebuild recommendations
I want to rebuild the 350 in my 1979 corvette and I'm not to familiar to the various companies and the longevity and quality of their products. I want to put in a 383 stroker kit and make as much power as I can but also I want it to be as reliable as it can. Can anyone nudge me in the right direction

2k rebuild won't buy anything. for stroked motor
this requires new crank, new rods, new pistons, new cam.
a good head rebuild will cost 1k.
you want stroked and power, your looking at 3-4k minimum.
I would suggested a balanced Scat rotating assemble.

realistic goal to have both you can make decent power and have it last dont get too caught up in dyno #
dont go crazy with lift duration rpm
Personally i stay away from real fast ramp cams. If you need more power just put a bigger one in it.
Is the owner building it or an hourly? Lots to look into
What trans gearing?
Budget?
Good machine work is most important to longevity
one can use not so fancy stuff but if machining is spot on, and you dont get abusive to it (revving it hard cold etc) it can last a long long time

well youre in a tight spot, any thing you put in the engine to make more HP needs supporting mods like long tube headers preferably, high flowing exhaust. Really need to know the gear to get the cam right. Ive got 2k in my short block, without gaskets, fluids, hoses etc.

go with a GM crate, lower cost and longer life.
P.S. the new stroker kits are 409 and 434. The 434 has a short life, the 409 is ok. That is what I also saw the most last summer. But they are not cheep.

also depends on your budget and determination. Your cheapest bet is to buy a rotating assembly, bore the block and put it back together. For a street motor you can get away with hyper pistons and cast crank and get 450 reliable hp with some vortec heads which are dirt cheap
crate motor is less hassle, but to make similar hp will cost you a bit
for many who go "all out" on parts, the rebuild will cost as much as the crate motor
realistically assess your budget, and that will drive how fast you can go

$650 is what it will cost to buy vortec heads, have them checked for cracks, planed to be flat, valve job, new seals, springs, and screw in studs. Unless you want to gamble with risking are they good or bad? Buy aftermarket and not mess with stock heads.

I'm rebuilding my 81 right now also, it is just as much to rebuild the 350 as a 383 so might as well go 383. That's what I decided with the help of the guys on here and some research. Call jegs or summit and they will help a lot. But with the engine work and heads, new rotating assembly, cam, carb, intake, and everything else. I'm probably going to be around $3300.00 Price is including long tube headers / high flow water pump. That's using my block which is .30 over already but just need honed and my 2.02 heads. If you want a copy of my parts list send me a message on here and Ill send it to you. If not good luck. I did find 383 turnkey engine's on ebay for 3300-3800 and up! But none were near me so that makes me uncomfortable if something goes wrong with it and spending close to 4 grand!
