I really want to go with the comp 270H for the sound, But my engine builder said i'd need more compression then 9:1 and id want more gear then 3.55's with a 4 speed, He also said I would need new lifters(engine only has 3,500miles on rebuild) and and different rocker ratios, because I might have a clearance problem and my springs would bind....Does that all sound right? I guess I have a edelbrock cam
Lift= Int. .448 Exh. .472
Duration at .050"= Int. .204deg Exh. .214deg
Is that cam pretty good?
thanks.

You'll need new lifters whichever cam you use, because you always use new lifters with a new cam.

The cam he recommended is better than stock, but it's a little in the 'why bother?' category.

You would need new lifters like Steve said. And also maybe new springs, depending on how much lift yours would stand before they coil bound. As for the compression, you are fine, as are the 3.55 gears.

You would need cam and lifters, and more than likely springs. The rest is just phooey (mighty technical term there huh? )

The 270H is a nice high power street grind.. Get the whole K kit and you should be burning tires any time you get ready.. You'll love it!! I installed one a few years ago.. No machine work was necessary.. I use the Lunati 292 grind now with all the same hardware left over from the 270S.. Very rumpety-rump until 2200 rpms.. Then look out!!

Actually, the cam you already have isn`t that bad. It seems that several different cam companies have that same grind. In my daily driver 302 5 speed Fairmont, I have that same cam, although mine is a "Blue Racer", but it has the same .448I, .472E lift, & 204I 214E @.050 duration. It`s pretty mild sounding, almost stock idle caracteristics, but I have gone high 12`s @105mph with that cam, shifting at 5500 RPM.
This was with the 69 351W heads (stock) that I put on my 78 Fairmont engine, with the stock 69cc heads, the engine would only pull to 5200 RPM with the same cam. Even though the cam is pretty mild, it hurt the 60 ft times at the track until I swapped the original C4 convertor for a 2500 stall unit. After I switched to the 5 speed, it worked better yet.

Thanks money maker, But i'd still need springs and could have clearance problems, and on top of that I have no one that would want to help me install it, and I can't aford to have someone at a shop do it. I can't decide I really REALLY want that cam!!!!!!!!!!!!!!!!!!!!! So i'd be spending 99 for the cam, 65 for lifters 63.95 for springs and 1.6 rockers that cost maybe another $60.00 so I am looking at $287.00 and I'd that would make me all set and have no probelems with clearance?
Oh yeah don't forget I have mid 80's 302 heads. shown here... http://images.cardomain.com/installs/113000-113999/113040_28_full.jpg

It looks like your engine is pretty much totally stock, right down to the exhaust manifolds.

To make use of any cam that is larger than what you've got, you'll have to do a little work on the heads and open up the exhaust system.

Unless you want to upgrade your whole combination, you're not going to pick up any power with a larger cam. Your present cam is about all your engine is currently going to be able to make use of.

Good Luck!

Those appear to be non adjustable pedestal style rockers. You can not turn them into adjustables for $60 unfortunatly.

Those are not rail rocker heads or valves.

Back when I had the original pedestal rocker heads on my Fairmont, I used Cranes kit that had shims to fit between the rocker pedestal & the "trough" that locates the rockers. If I remember correctly, they have .030 &.060 shims in the package.
