Wow. Out of the box it is over 1000HP. How far under could you go! Ray

FS/AA at 3332 minimum wt. and FS/A at 3620. It's cool that Chevy built one. Wish Ford would do something like that.

I saw the one they had at Barrett. Who makes the aluminum heads for these?. Edelbrock no longer shows the rectangular port aluminum heads in their catalog.

I believe the heads are a spread port designed by Chevy for this engine.

Should be a quick combo for example my A/H Hemi the NHRA has us at 505 and we weigh 3200

Well, that`s a relief! I thought maybe this was the reason that NHRA brought in the SS/QA class, in case Chevy was able to convince NHRA that the 632 should be rated at 180 HP!
