renix camshaft in a ho block

[Mike1331]

I've read somewhere that the renix cam's had better lift/duration numbers and that they needed this tbecause of the horsepower loss with the egr. Has anybody tried putting in a renix cam in a stock ho block to pick up a few extra ponies? I'm about to switch to a ho block and am thinking about throwing in the cam from my renix motor...is it worth it?

I haven't run the numbers, but I know it will fit (mechanically.)

The AMC sixes - 199/232/242/258ci - will all accept the same camshaft, will swap crankshafts, and use the same screw patterns on the heads (1975-up on the heads.)

If you're just using the HO block but the Renix intake / injection putting in the Renix cam will juse make it a Renix.

The differences between Renix and HO are as follows:
Intake
Cylinder Head
Fuel Injection System
Exhaust Manifold (Difference is really only with the EGR bung and O2 stuff)
Cam

The only other difference is '96 up has a crank girdle.


Right now I'm running a '96 Block with a Renix head, intake, and all that. I am using the '96 camshaft and have no issues. It's not really powerful but it's pushing 35's and lift and all that crap.

Aside from that I wouldn't bother with an HO injection swap, more trouble than it's worth, the Renix system rocks!

yeah i've read gobs of threads on this swap, i'm pretty set on everything i need. I found a 98 block with 70k, i left the head on and i'm putting renix intake exhaust on it. I thought the renix cam had a slightly more aggressive profile. Does anybody know where to find these numbers?

The renix-->95 HO cams are the same. I've read that the cam in the renix is advanced some degrees to bring more low-end power. Someone needs to compare the two fsms to find the differences on installation/different timing sets used and maybe we can come up with a #.

thanks for posting that, now if i only knew what the numbers meant. it looks as though the ealier cams have slightly higher numbers than each of the later ones. Does that mean the earlier produce more power?
