This is just a basic 10.4 comp street build slated for a heavy '70 Charger with 3.55's and a 4spd. It's a 440 Source crank, Eagle H beam rods, Icon dished pistons, Comp street roller with 246 @ .050" .630" 110 LSA, Howards Hydraulic Roller lifters, Edelbrock 5090 cleaned up/VJ/Resurfaced, 383 Torker , Holley 950 XP. So far so good. Previous customer's engine was a 470 B with Maxwedge Pro-comps etc.... More horsepower but about 50lb/ft less at a much higher RPM.

I used a Trick Flow intake rather than the Torker but everything else is pretty close to what you have there. Mine idles at 950 rpm with 16 inches of vacuum but pulls hard in every gear.

My Moparmate bought a 470ci ex-Landy 400 motor that was in the 'Engine masters' It made 700hp with 'new' back then 572-13 heads. It was a screamer, but fell apart real quick lol... The main-caps were the biggest set-back so we fitted program 'batwings' 4-bolt caps and all was good... Last edited by Gtxxjon; 07/13/21 01:35 PM.

Completely original car with 3.23 gears and runs 13 dead in the quarter (in drive). Crower street roller 0.550 lift Best bit is the carb a 950 HP Holley that gets 17 to the gallon... Imagine that engine in a Dart or Barracuda... Last edited by Gtxxjon; 07/13/21 02:02 PM. Carpe diem, quam minimum credula postero, thanx Horace!
