71 Dart 410 stroker ..
What are the Et goals again
Hard one to guess at...the old 360 exceeded expectations....never did I expect it would run a best of 10.54 in Vegas or 10.31 in Bakersfield...I should have just replaced the head gasket and left it alone...I believe it started out running 11.20s in Vegas...but the engine got faster and the car suspension got better...and lighter...
Anyway....the obvious 40 cubic inches more...a lot more torque....12 to 1 compression vs 11 to 1 compression.. next size bigger cam...hughes 264 vs hughes 260 ....
lighter rotating assembly then the 360....Eddy heads are Fresh with 2.08 intake valve...
two things that i have questions about....torque converter and rear gears...going to start with the 4.56 in rear (dana 60)...I think it probably should be 4.30s....will find out in a few weeks....what kind of rpm the motor runs....has good parts...but usually run the rpm conserveraly.
torque converter....was using a TA 4400 series converter....flashed 5200 ish with 370 cu in motor... I elected to go tighter with a TA 3800 series....It would flash to 4800 rpm with 360....so I would "guess" with 4 inch crank...it would flash around 5000 .....
So Friday sept 8 we have a TNT with a Sat/Sun bracket race...get some passes in...get rings seated...and one more race on Sept 23......after that we will make some decisions on the torque converter and gearing....as Nov 4 and 5 it is heading for some cool air in Bakersfield...
I think this engine will have an easy 50 hp advance of the 370....once everything gets sorted out...So I would expect it could run 10.30-10.50 in Vegas depending on the weather...but as I say..the clocks don't lie....So what does it run in Bakersfield....lol
