TPI Performance Upgrades
Hey Everyone!
So, I finally got my 350TPI in my family's 1965 Chevy C10 and I am LOVING it
So, as a good Hot Rodder I cannot leave well enough alone! So, I am building a list of performance upgrades! I wanted to run them by everyone out here and see what you think.
Right now the motor is mostly stock. I have deleted ALL smog equipment AND the EGR. I am running 2" Chevy Ramhorn Exhaust Headers for now. I am using the SAUJP v5 tune. Stock heads, stock porting.
Upgrade thoughts:
Exhaust to 2.5" Ramhorns
1.6 Rocker Rollers
AFPR
Chevy Performance Hot Cam LT4 24502586
Valve Spring Upgrade
Electric Radiator Fans(right now running a mechanical fan bolted to the water pump with no clutch, sucking lots of HP away)
Port TPI
Obviously new Tune
Possibly new injectors after all of that.
Thoughts? Any idea what flywheel HP/TQ will approach if all of that was done?
Looking for honest input here, good and bad!
Pics Attached!

Re: TPI Performance Upgrades
there is so many builds on google id start there. The reason is, there is full builds with dyno numbers to give a great idea on which direction and money you want to spend.
long tube headers, new cam, tune you should be approaching the 300hp mark

Re: TPI Performance Upgrades
If your really serious about upgrading TPI, then you need to add a few things to your list. Get a used set of SLP runners and port them. Port your plenum. Either have your stock heads ported or go with a set of better heads, Vortec, Trick flow, AFR, etc. From what I have read on this forum, the LT4 Hot Cam is a bit too much for TPI but still a good choice. Then Tune, Tune, Tune.
