Then when you want to yank the engine, add cam, heads (if no rebuild bigger chambers) to get compression down to 10.1. Otherwise if you want to do a cam change while in the car I would recommend a custom cam to work with what you have as far as the long block. Oh well, I can pretend right?? I thought that the stock 351 was putting out 230 or so from the factory.. According to the desk top dyno, I think I was a little closer to 270hp at 4000rpm.. And aftermarket heads brought it up to about 330..

All the perf upgrades are going to cost you $$. there are allot of little changes that are cheap DIY's, that don't cost $200-300-$400. Pertronics ign and coil, then open the plug gap. Re-jet your carb, K&N air filter, advance the stock timing to 10-12 degrees, etc, etc. this are little inexpensive things that can be done up front before you dump big money on HP parts. But, if you got the $$, exhaust, re-jet carb, intake, cam, and last but not least, heads, in that order.
