Easy HP for 350 TPI?

Hey guys, Ive been reading this forum for a while now but there is so much info here it is hard to take it all in. Ive got a 1987 Formula 350.
Right now the only things done to the motor is a bigger cam (and exhaust if you want to count that) The motor is putting out right around 250 HP, maybe a little less. Id like to increase that, Im not looking for a million horsepower here but would like to get as much as possible without getting to serious with it (bored/stroked etc)
What are some easy bolt on things I can do to increase the power or anything I can mess with to do so?
I was thinking about looking into a performance chip after the idea was brought up to me, thoughts?
Thanks guys

-Jesse

The easy and free mods first;

Skip the "performance chip". Investment too much $ for the return. Look into custom chips when you get to the point that you're ready to start upgrading internals and or major external bolt on's.

Re: Easy HP for 350 TPI?

do your own chip tuning for that car, its easy to do and learn for MAF sensor cars.

How big of a cam did you put in? it may need a tune for it to get the most out of it. 250whp is not bad for a stock tune/stock TPI cammed car depending on the cam size.

The other easy gains would be TPI bolt on parts or a different manifold all together, like superram, miniram or my favorite, the stealth ram by holley. I picked up alot with my 89 TPI 350 by going to the stealth ram
