Just sharing some info from a 408 we had on the dyno today. 515 rwhp and a converter flash over 600rwtq.
Specs:
TH-400 trans( car set up for N2o )
6.0 block, 4.030
4.0 stroke
stage 3 6.0 heads (330 cfm)
solid roller cam set up for N20
ls6 intake
ported stock TB
These are just the prelim #'s, hopfully in the high 520's when done
Hopefully we will see a 6.0 block go in the 8's

Time passing and R&D sure pays off, smaller portvolumes, attention to detail and programming sure make the diff.

Thanks Nick, sounds great I'm building a 408 ironblock just for the track{1/8mile mostly,we don't have a1/4 close by]want to use a big solid roller cam probably around 260 @.050 with .670 lift ,110LDA??tThinking of using ported 5.3,s Jesel shaft rockers 1.8 rr, maybe aluminum con. rods, electric w.pump ,fabricated aluminum intake,not sure on pistons yet maybe Diamond or C .P. What do you suggest? BY THE WAY I LOVE ALL THE WORK I'VE SEEN OR READ ABOUT FROM YOUR SHOP!! Thanks Mark.

Thanks Nick, you must think I might have trouble with the 1.8 Jesel, I will be running some big springs ,I'll lose about.037 lift but I guess that'll be OK,should be about.636 with 1.7's.You think I should run more duration,they have 268, 264, 260, all with the same lift? This is going in a gutted car 2500lbs 4-link rear,. 4.88 gears 4500-5000 stall with a powerglide ,plan to run 2 stage no2 after I get the motor sorted out.probably will see 7500-8000RPM.
