Not sure what I have forgotten but tuning at 15-17psi if the new clutch takes it. I would expect 500hp on premium pump fuel and 600 or more on E85 with this sort of combo but only time will tell
DUUUUUUDE. That thing is sick ! I love the gold as well, Im thinking about doing some sort of AMC Metallic blue or that Mopar gold color too with some flake on just the block ! I'm leaning on the blue to stick with its AMC heritage but this video after seeing the gold makes me want to do a glossy and metallic gold ! i'll see what color i want 😆
Man i so excited for ya man 😁 It looks damn good !
Its good to see this thing "alive" like you said! I cant wait to see how it does and performs once its in the jeep
Im in the current moment of waiting on my machine shop for them to even touch my block for machining, a good amount of forged goodies will be in it from Russ pottenger and to mention i will be doing a stroker! I was gonna do just a 4 Liter build but piston speed isn't much of a concern IMO since you really cant get past 5800 supposedly cause of Cam harmonics and it breaking double roller setups like you and i are !
So with a 4.5L i should be good ill keep the Rpms below 5600 daily, It will be N/a for about 2 years maybe, ill be doing a 8.3:1 Dcr and a Static comp. of around 9.4:1 or so i should be Ok with the nitrous it will see and a turbo, The aluminum edelbrock head should help too with any pre detonation to an extent compared to iron! Will run an ARH header too so induction wise i should be pretty good !
Awesome
Hi what rods model using for engine
Just eagle Sir forged rods, since plenty of guys are spinning these things in excess of 600 horsepower on factory rods I didn't think anything else was really necessary for a street Cruiser
