Hey all im building a street/race a15 large port head big valves quad throttle boddie EFI knife edge crank 79mm pistons blah blah blah any one got any good cams they recomend? race perferably...Thanks Kyle

Guys, i need help. Is there anyone planning to sell off an A15 modded cam. A 270 or 280deg intake will be great. I have trouble finding for one. If anybody can provide me a link where i could purchase one from my country, that will be superb..pleaseee help me guys. My DCNFed ported head and A15 block is craving for a cam. Thanks alot...

The recommended compression ratio for a camshaft like that using A12GX induction is:
* for use with regular grade gasoline: 10.0:1
* for use with premium grade fuel: 9.0:1

Now the cam grinder may have his own recommendation. There is no exact science here.

You should be able to use the 9.0:1 with regular gasoline in just about any country. The aluminum head allows about 0.5 extra ratio over a similar cast iron head.

Cheers Benny!!
