408 changes..what do you think? Ok guys here are my dyno results from this past October.
I just dynoed my car today and it made 496rwhp through a th400/4000 stall and an 8.8 in a foxbody mustang. Here is what I have...
Iron block 408 11.5-1
K1 crank and rods with wiseco -3cc pistons
Comp cam 247/255 .624/.624
Very mildy ported l92's, ls3 rockers with comp trunion upgrade
Victor Jr carb intake
Pro systems 1000hp
1 7/8 dynatechs with 3"exhaust
Th400 with 4000 stall
8.8 with 4.10's
Car ended up going 10.30 at 133, shooting for 9.70's this year still on pump gas and NA
In the process of making some changes, old cam was on a 114LSA which was def not ideal for my setup. New cam is a 247/256 .650/.650 on a 110, new converter is an 8" 5500 stall, moroso oil pan, and a 150-200lb diet.
Just wondering what you guys think these new changes are gonna do for me....

What's the car weigh now? What's it 60fting? Are you leaving on the T brake or foot brake? I think the new cam will help especially with the new converter but you may end up having to do a gear swap to some 3.73s or 3.55s. When my blue Fox was setup for motor it had 4.10s and an 8" spragless 5000 and a TH400 28" tire. It went 9.77@139 on the limiter at about 1000ft 1.43 60ft. I then got it set up for the dope with 3.50s and a 3800. You may just squeak by into the 9s with the 4.10s though if the car leaves hard.
