OK, so I am finished with my 5.0 to the 5.7 swap with rear axle swap as well. All running pretty smoothly, but I am wondering, how much horse power is capable from this motor leaving it as a TPI set up with out adding Nitrous and staying normally aspirated? Any ideas?
Any recommendations as to what my next modification should be?
Thanks all!!

 

There are several here that have dyno sheets for 400 HP w/LTR's at the flywheel but it appears to be a lot of work/money. Headers/exhaust, heads, cam, intake, in that order. And, a razor sharp tune. Unless you're going racing, don't be too concerned with horsepower numbers. Enjoy the torque of a TPI on the street.

 

for cheap but a lot of hp go for cold air intake exhaust and afpr

 

OK, so my blonde is going to show on this one, but what is AFPR? and any recommendations for exhaust/cam/head combo's...there are just so many of them and I am not made out of money to just start trying stuff. which i am sure most of us aren't.
