I don't get why dyno numbers are so important to people. That motor would not make 100 more hp with that tune and that transmission on that dyno just because it's in an f-body. It's just a number.
Lol exactly.. Everyone wants a dyno queen
Numbers are nice to have....
But speed and et is what matters
Again you have to get that power planted to the ground

Sorry i haven't posted any pics yet been busy with work and other things. But, i got the motor apart and to find the crank was junk. It could be fixed but might as well do what i wann do the first time and go ahead and build a 408. I ordered the rotating assembly last weekend so, hopefully itll get in soon then i can order some heads that ive been eye balling. Ill try to get some pics up in a few days
I'm going to keep an eye on this one. I have a F1R combo going together here shortly as well...I'll be using the F1R at first since its just sitting there and when everything is sorted out I'll step up to a F1X or F2. I'll be running a 6spd though so it'll eat a little less through the drive train...aiming for 1000-1100 but the motor combo will be up to the task.

glad to see you are making some progress. dude is right about the numbers not being important. I personally dont care what people say it makes. I am a person who likes to be at the strip. The timeslips are all I care about.

With the cubic inch being a 347 I assume you have a four bolt block and head combination. Max boost with a centrifical supercharger on an aftermarket set of heads with a thicker deck is normally around 18 to 20 psi before you have to worry about lifting the heads. This boost level can be achieved with an F-1A on a 347, and the F-1A will eat up less hp to spin it than a larger blower will.
Hopefully this helps. Bob

No offense, as I know you have been around a long time, but you can run way more than 18-20 psi on 4 bolt stuff with prochargers. Its about the tune up and fuel........It's not 2004 anymore.
My old set up was 23 psi no problems and my new setup 408/f2 makes 30 psi and I'm still on 4 bolt heads. No lifting so far.
