Not trying to be snarky here but I noticed your thread post said simply "Help". Not too many responses, I edited the thread so we can get some feedback for you. Clarity in the title helps.

My opinion: Do a little research on a good small block. Jegs, Summit, Goodwrench have some good crate motors, probably cheaper than what you would pay to get your engine rebuilt. Your accessories (alternator, power steering, etc.) will bolt up without going through the hassle of finding new brackets, hoses, whatevers...a simple bolt in, plug in and play. How much horsepower you want is only limited by your pocketbook. I didn't notice your location but if you need to play by the smog rules, be careful. Dan

"Jeg's, Summit, Goodwrench crate motors..." Yes, probably cheaper. You get what you pay for. While a "custom" engine may cost a little more and you have to "wait", it will blow the DOORS off the craters and usually use less fuel and last longer. So, which is more important? That should be the decision "maker". And yes, this statement is being made by a machinist that builds some of these "custom" engines. Take it FWIW.


BBC? Do you want "big" power? Lots of torque and low-speed power? Use the big block. Old sayting: "Never send a boy to do a MAN'S job..." If under 400 lbs. of torque and higher revs are what you want, the small block is where you should go. A high quality rebuild on your 350 runs around $3K. The big block will be significantly more money (nothing RARE about big blocks, just expensive for parts). Again, you get what you pay for. BBC may be the best/most versitile powerplant ever made for automotive applications. The single biggest drawback is the sheer weight. For high-revvers, lots of attention needs to be paid to the valve train.

If you're money coscious, and on a budget forget a 383 stroker. Most stroker kits to fit a 350 will run around $1400-$1500, and then you need a good 350, plus the rest the parts to finish it off.
I'd either find a good running 454 and do the swap, or replace/rebuild a 350.

not to piss on your grapenuts, but
g.m. sells a vortec headed, rooler cam, ALL NEW PARTS, 350 for 1990.00
with 9.4 to 1 compression (so lets call it 9 to 1 as it's not bluebrinted)
and will go 200k miles easy.. and 320 hp easy ..
big block in a truck unless you are towing, or a weekend toy, is a total waste. as you'll never get the power to the ground.. without tons of money spent.. and at 4.oo a gallon plus.. not worth it.. unless you need the low end to tow something..
