So I picked up a monte carlo ss with a 385 stroker that I plan on putting into the camaro with a HSR. The engine has less then 500 miles on it but has a flat cam lobe, so I need a new cam, I have been told the cam in the car is .525 lift, it had a good lope at 1000 rpm. Now I have been looking at some cams but I was leaning towards the comp cams CS 280H-10. Any opinions? Heres my setup right now:
385 stoker
113 aluminum heads
1.6 GMPP roller rockers
Flat top pistons
pro comp single plane intake
edelbrock 750
built 700R4 with a 3500 stall converter
4.10 gears

 

Call the cam manufacturers hotline and ask them. I would however switch over to a HR cam, less chance of going flat on you, but if you must use a flat tappet cam get a zinc based lube for install and some zinc additive or it will be flat again in short order.

thinking about this one

 

It runs on pump gas? That thing is near 12:1

Gonna need a big stick to bleed that compression off. Sure it has flat tops?

 

I'm not just what I have been told, the guy said it can run on 93, but should be mixed with race gas. I was running it on 93 without hearing detonation/knocking. I need to get a borescope down the plug hole. The cam appears to not have had proper break in, or just a bad lifter as the rest looked fine.

 

Yeah flat tops and 64 cc in a 3.75 stroke is 11:1. 113 heads are 58 cc and could be approachin 12:1, i didnt run the calcs. Be careful with it

 

I don't plan on getting on it unless I'm running race gas. Might do e85 when it goes in the camaro
