Building a 340 stroker with factory J heads, 2.02 intake, 1.60 exhaust, bowl ported. 4" stroke, target compression ratio of about 9.8:1, factory 1970 340 cast iron intake, Edelbrock 750 AVS, 340 HP exhaust manifolds, 727, 3.55 gears in a 1970 340 Dart. Flat tappet cam. I was looking at some of the Lunati Voodoo cams, but would like to hear some suggestions for this stock appearing 1970 340 Dart.
Thanks Darren

You didnt say what purpose this engine will be used for.. street or strip or race only Considering the mildly reworked heads, cast iron intake and exhaust manifolds, I think we can assume street motor. And a mild-ish cruiser at that. The OEM exhaust manifolds are going to strangle potential performance. They were OK for 340 ci, but are going to choke a 416. The cam should be designed to help compensate for that.

FWIW, some years back I had a 406" LA, iron heads, T-quad on Eddy dual-plane intake, cheap/small headers, A/T, 3.23s, AC, street Duster. Went with an Engle FT hydraulic 214/224 @ .050, .470/.504, think it was on 110 CL. Had perfect street manners, a nice bark & lope, pulled very well, got 17MPG @ 70 MPH. On an iron-head LA stroker, 9.5 is about max CR on 91 unless you've got a lot of overlap to bleed dynamic CR.
