\I'd say Comp, that's the box my stuff came in.

 

Damn nice #'s, I might have to call you guys up when I get my new set of heads.

 

Nice numbers, I have seen a few cars on there make 415-420rwhp with 100K on the stock short blocks, so a new short block, makes sense.

 

nice #'s..i wish i had an m6 and 10 bolt to free up some power for the dyno. j/k. nice setup

 

Pretty sure it's Comp. FMS uses Cam motion for sure.

 

Once we order a 12-bolt, she will be back out there racing. Maybe around Christmas time. I don't think the stock rear is going to last too long.....

The cam is from Comp.

 

What about a Dana 60 Jason?

 

Nice #'s!!

 

They are ~25lbs heavier than a 12-bolt and slightly less efficient, and very overkill for what she will be doing. I have had very good luck with 12-bolts being very durable and staying quiet when setup corretly.

 

I thought since that being stronger and cheaper would give them an edge over the 12-bolt, even though it's overkill. Guess they just aren't proven in F-bodies yet.

 

Nice #'s but maybe too much for a girl to drive! j/k..

 

Haha, you should race her then...

 

If so, then let's delay it till she gets a stronger 12-bolt rear..haha

 

Is your bench real conservative or does TEA's read high, the stage 2's are supposed to flow 280+cfm. And whats the runner size on those heads?

 

Thunder's SuperFlow 1020 bench is a bit on the conservative side. It is ~15cfm lower than TEAs at peak. TEA also flow their exhaust with a pipe; the exh. flow numbers listed in the first post is w/o a pipe.
