What would be the best engine combo for a turbo? Should I just do like a 355 or something bigger like a 383 or 396??

 

Turbo's seem to really like cubic inches from stroke. I have seen dyno numbers from two small block ford 383's with different bore and stroke. Everything else being as close as you can get the engine with the larger stroke made alot more average power. I don't remember the specific numbers between the two motors but both were around 1900HP, I just remember the stroker was ahead.

I would go with the 383. I know it was close finding low compression pistons for my 3.75 stroke and 6 inch rods.

 

I'm running a 383 with 6" rods and 8.5 cr. The more the cubes the better..

More cubes will load up your turbine a lot faster even if you are spinning a bigger turbo or even a bigger A/R for that matter. Less lag is a good thing while still being able to flow more top end air...definately, definately go with a bigger motor if you can afford it.

 

well, i'm going to go against the norm and say that cubes are not as important as people think UNLESS you have very large turbos and you need the extra torque the cubes provide to spool those turbos, otherwise pic what you want

The compressor is really what is going to limit your horsepower potential, the only thing that a bigger motor is going to do is give you more OFF BOOST torque.

Thanks alot for the replys. I was thinking somewhere along the lines of a 383 or 396, but wanted to make sure it wouldn't be better to stick with something simpler like a 355,etc... Thanks again.
