well I went to a dyno GTG from the DTW site. They had invited me to join them over at Flat Rate Performance in Pearland.
still havnt got any tuning done for the cam havnt had time.
but I was well please with the numbers, on just a cam swap, and no tuning
old dyno numbers before the swap where
HP = 258.2
TQ = 253.4
this was at 91.4*F 30.17-0.90 in.Hg. 0ft. CF=1.01 rpm/mph = 78
new numbers, after the cam swap.... no tuning except for just to get it running.
HP = 268.3
TQ = 325.5
this was at 95.6*F 29.94-0.76 in.Hg. CF=1.02 rpm/mph 47.05
I also got the MPH recorded on the dyno.
max MPH was 148MPH
the Dyno was a DynoJet dynometer.
I am very happy with these numbers. and believe 13's are in reach on all motor
I will be making a trip to Allen in a few weeks to get it all worked out

I thinking the 325 might have been a spike, the graph jumps around pretty good at the end. but thats what it recorded on an all gear pull.
I had to manually shift from 1st to 2nd, and the 2nd to 3rd, and 3rd to 4th, to make that run.
when I let the computer shift it. my HP stay aprroximatly the same but the torque came down to 278.2 ft. lbs
still thats a 25 ft lb jump. with just a cam swap.

Thanx
Hope this works for ya Cam Swap Page just print this out get all your gaskets and new bolt, some antifreeze and some time and dive into it. I got the gasket and all at the local stealership for about 40 bucks...Zed
So that looks like springs retainers and possibly pushrods. Would 918 srpings work? A guy in here has a set for sale.
Thanx storm with that I think I'll try the install myself.

Those are some good numbers bro. But don't get upset when you get on a "REAL DYNO" and drop a few numbers. BUT, still great numbers.....When are we going to run them????
