I have a leaking water pump so I figured while I fix that and have everything out of the way I might wanna add diff. cam. I couldnt tell you off the top of my head the specs on the current one I have; its nothin to radical.

Justed wanted to know your guys opinion; lookin for somethin that would give my 302 good power... you can see my mods in my Sig.

 

comp cams Extreme energy 268. .512 lift and 280 duration. I run it in my 302 and its awesome. Whats your compression ratio because that will have an effect on how big of a cam you can go.

With all the edelbrock stuff you have try the RPM cam. I have it and really like it, plus it is matched to the heads you have.

 

I'm a fan of that XE268H cam as well. I ran it for a while in my 331 and it worked out well. You've definitely got the gears for it.

That, or the Performer RPM cam, seeing as you've got the rest of their power package already. I'm partial to the Comp Cams grinds though. They tend to grind their cams for better power across the rpm range, not peak power for a narrow rpm range.

 

stock pistons?
rods?

if yes then make sure the cam is designed for best performance below about 5500rpm.

you realise you need to change lifters too? Sorry if thats a stoopid questionit just read like the water pump out of the way means the cam could be easily changed.

 

Hrm, I forgot about the bottom end. That XE268 cam will wind all the way up to 6k, which is much farther than I'd trust a stock bottom end.

 

Get a roller cam. You'll get better mileage, make more power, won't have issues with most of the newer oils that hate flat tappets, and it'll be more reliable and last longer. With your gears you could get a cam rated up to 6,000-6,500rpm and it'll still be drivable. For a street car I'd get something rated to 5,500-6,000 though, you won't really miss the top end power over a larger cam, and it'll still have plenty of getup and midrange.

 

A roller cam conversion isn't something you can justslap in. You either need a spider assembly to keep the lifters from popping out of the lifter bores (which requires some drilling, which isn't a good idea without tearing the engine apart), or you need a reduced base circle cam, which can have its own set of problems.

 

The roller conversion cams work well, they just cost a fair bit. But given the crap oils they make these days, and the increasing problems that flat tappet cams are seeing, the extra money spent on a roller cam is worth not having a cam come apart and throw iron filings into the engine. It's cheap insurance, and like I said, they make more power with better mileage, and generally have much better manners than a flat tappet cam.
