RV Cams?

Ok here is my two cents here. Small Block chevy engines are probably the easiest engines to make them produce horsepower. An RV cam is made specifically to give more low end torque rather than horsepower. that being said. In the 85 86 the heads were the biggest problem. The engines were produced for the smog and low horsepower and torque ratings were the result.
I can assure you, The 350 that you have is capable of producing plenty of horsepower and torque to do what you are trying to do.

Carb intake Headers and heads will put you where you want to be. If you dont change the heads you will see limited results. The heads have very small valves and intake runners making them the weakest part of your equation.

Here is what I would suggest.
without replacing heads,
Go with a good RV cam that will increase your torque.
Headers and high flow cat and good perfomance mufflers and dual exhaust.
600 Holley with vaccum secondaries.
Use an elderbroc dual plane intake manifold I beleive an air gap intake would suffice.
If you can afford it and are willing to, buy a set of elderbroc performer RPM heads with 64 cc chambers and 170 intake runners.

I have a 1986 350 in my 1969 chevelle it has not been bored and it is still 350 cubic inches. I have elderbroc heads and a huge solid race style cam. I forgot to mention I changed pistons to 12-2 to 1 pistons. I am running a victor JR intake and have a 930cfm holley. I have had it on the dyno and at the fly wheel I am making 485 horse power. so yes the cam intake and headers and exhaust will help. The heads will be your biggest gain.

Good luck!!!
