sup guys.. i'm starting to write out a plan to build an engine.. just wanted some tips on where I should take it.. I know I want low to midrange power, 2000-5000 RPM is where I want the power to be.. I'm gonna start off with a 350 block and put a stroker kit in it.. I want it to be ready for forced induction, not sure if I wanna go with turbo or supercharger yet, but I know i'm gonna need low compression heads/pistons and a steel crank.. I also know what I want for headers, 1 5/8's tri y, probably doug thorley.. before i put the forced induction, I want it to be pushin about 400-500 horses, if thats possible without completely destroying my gas mileage lol anyways, gimme some feedback.. thanks!

 

Im pretty much in the same boat as you. except im looking to build a N/A motor with a 3500-9000 RPM power range. For what you're looking for I think I'd personally go for the more expensive forged crank while you're at it. Bore+stroke it to 383 or 388. Go for maybe 9:1-ish compression forged pistons. Make sure your heads flow pretty well. I dont think, w/o forced induction or spray, that 400-500hp on low compression is possible. As far as turbo vs blower go, it depends on preference and more. A turbo is usually more efficient but the power isnt always there. On the other hand, people have told me the blower killed their mileage but the power is there whenever you want it. A turbo setup can be bought and self-installed for a decently low price(roughly $1000) some fab work required. A mini blower(about 40% hp increase) would run you probably $1500 or so IDK I havent priced them recently. Or the full blown supercharger setup would run you over $3000. Biggest bang for your buck, personally I'd say turbo. If you do decide on turbo be sure that the turbo isnt too big. If it is, you wont hit power until about 3200 but it wont run out till much later than the 5000 you're looking for. Plus, if you set your boost REALLY low, it can increase your mpg's(thats part of why chrysler had a thing for turbos in the 80's). I'd say go turbo, get a cam & intake that are good for idle to 6000-7000 or so, get a decent sized turbo that would be fully spooled by about 2000-2500, put your foot down, and have fun. probably shouldnt run high boost until you have a rear that could handle high hp. When looking for ways to route a turbo setup, take a look into the power adder section of the board. If you feel really motivated for power, try a twin-turbo setup. I know on imports people have had success running a 15G turbo with a larger Super 20G turbo so that once the 15G is out of juice the 20G is spooled and making huge power. One of the most ridiculous/expensive setup around is running a supercharger AND a turbo or 2. I believe this is also how the hennessy vipers are set up.


Anyone disagree or have something to add feel free to correct me. Im no expert and wont pretend to be. I simply know several people with built motors, have a little building experience myself, and have done tons of research on this setup

 

i would on the contrary recommend a supercharger setup, its easier to install and doesnt require all the fab work. and its pretty self explanatory
