I was wondering what is the best way to get more horsepower from an 87 305 tpi motor. I have already had head work done, headers, port and polished. What else can be done?

 

Cam it and tune it. A new intake setup might be benificial as well.

 

Agreed. Intake, cam, and tune.

You could go all new intake or port and get runners for the current TPI. Would be very beneficial to match to your current heads.

 

Thanks for all the help

Sorry i forgot to list i already but i already put in a high performacn roller cam. What would you recommend for intakes?

read my sig for more ideas and average results with zero tuning as of yet.

 

My opinion, and hopefully some more will chime in...

The cam is not large and the gears are not too big, so I would stick with larger runners, larger base, and ported plenum. If that is not enough in the end add a power adder for more power and a little more help in the higher RPM range.

Either that or do the superram for a little more rpm range, but I don't think it would cost effective for you considering it likes single pattern cams.

 

Modified LT1 intake. Should work pretty well with the cam you have now.
