Hoping for 420-460 na RWHP , we'll see as soon as the break in stage is over. Man some great numbers out of other 396 setups , hope I can make good company!

Well before I had a 105000 mile shortblock with comp 224/230 112lsa pro mag 1.6rrs
Jethot longtubes,home ported heads and k&n cai I put down 350/350 with alot of false knock(bad sensor)
I was trapping 112-114mph
that plus 100 shot I was trapping 123-124.xx
Now I have a APE built forged 383 11:5:1
and will be doing a 150-250 shot and a much bigger cam
No numbers yet cuz the motor isnt in but im guessing on just motor theres no reason why it shouldnt hit 400/400

The big concern on LT1 heads is the guides in both runners, taking some off the down side of the exh side, and polishing the chambers and getting just the right wave in them to make good turbulence w/o sacrificing flow.
