all stock small block 9:1 compression 76 cc heads 194 1.5 valves. can i use the xtreme energy 268 in this motor ? comp says largest cam with stock converter,can i use alittle looser converter , like a holeshot 2400?

that cam works well with a dual plane manifold. Stock converter should be ok. I have ran that before with stock converter, and a performer intake. Makes good low RPM torque.

im in a bind. i want to keep the stock converter in the car but i want to upgrade on the camshaft i want to make sure i have enough compression
83 camaro
342 gears
350 turbo
87 350 block standard bore
8.5:1 pistons
.015 head gaskets[should give approx 8.9:1 compression
76cc heads [stock] 194 intake valves]
the car may see 500 miles a year [very limited street]
jegs recomends 270 magnum
i have xe 268 but im concerned with compression
i was just wondering anybody put a cam in something like i have and what did you use,and did it work well?
no computer no emmisions on this car
can anyone help me in choosing the right cam?

voodoo 60101 or 60102 wich would be better in my application

Glen;
I just put together a '84 305 z-28 mtr with that cam. I have 58cc heads with 1.94/1.5 valves. Flat top pistons, EPS manifold & 600 carb. I went with a 2400 torque converter and glad I did. It would be a pain to drive with a tighter converter. If you're running a 350, it won't be as bad. The cam instructions say to run this cam with 9.5 or higher compression.

I ran the magnum 270 in my 86 silverado last year with 3.73 gears, 700 r4 tranny and a stock convertor and it ran perfect in my opinion, I used a performer intake and a 600 edelbrock carb, it originally had 76 cc heads with -12 cc dish pistons but I needed more compression so I switched the heads to some 305 ho heads that were ported and polished and it pushed my compression to 10.3 to 1 , that really woke that cam up, it would pull hard from idle to about 5800. I wouldn't advise running that high of compression though, I'm just lucky it didn't detonate with compresion like that with a cast head, guess I did something right, the guy I sold it to says he's never had anything with that much power and torque that was so easy to drive.
