5.0 tpi peformance upgrade insight
I recently purchased an 85 iroc w/original motor and trans(5.0 tpi and 700r4,unsure of read end specs).I've decided to stay with original motor,now I'm seeking guidance on best performance upgrades(cam,headers,exhaust,heads,injectors,etc. Is the edelbrock hi-flo tpi kit worth buying?,what are some good upgrade to 700r trans?My personal research showed that my engines horsepower is rated at 215 and torque around 225. So to get those numbers around 350+ would be ideal. $2500 budget(no procharger,turbo,or nos)
Thanks

I wouldn't spend much coin on the 305, headers / free flowing exhaust and upgrading from the 870 to the 165 ecm would be a good start.

You'll need a decent amount of money to get it to 350 hp. Headers and 3.42 gears are always a good start.

You'll probably never see 350+ HP with a NA 305 unless you spend some major bux, way more than it would cost you to build a nice 383 with more HP.
