We don't call them Hemiroids for nothin Now, if we had a double overhead cam hemi in production that could possibly resolve this debate NOT I was suprised several years ago when I built my first pump gas low compression street stroker motor that ended up making 1.37 HP per C.I. with a set of ported 906 iron heads. I was building and dyno testing a lot of motors then and I had not had a pump gas 426 Hemi make as much HP or torque per C.I. as that low deck wedge stroker did Still haven't That 512 low deck motor had absolutely no quench, 22 CC dished pistons .025 in the hole with a .042 thick head gasket and I used a stock low deck Edelbrock six pak intake and factory vacume carbs. I guess my message is anyone can make power with a wedge, not all of us can do the same with a 426 Hemiroid Maybe Ma Mopar saw the writing on the wall( 426 Hemis don't work as good as the L.A SB do HP per C.I.)) and decided to quit making them(426 hemis) and blame it on the govement emission rules and insurance companys



FWIW my first go around with one of these things did bring a few things to light. Previously I has a 496 wedge with a .650 lift 290 duration roller cam, 1050 carb and eddy heads that flowed around 310, and had 11.2 comp. that engine made 630HP/650lb.ft of torque. It was all done at 5800 and made max torque at 4000rpm.

The Hemi is a 472, K8 Hyd cam, MP single 4 intake, 9.5 comp, and intakes that flowed around 320 (this was the first go around). It made 6000Hp at 5800/585lb ft of torque at 3500. It seemed to me it was a lot easier to get the performance out of the Hemi without going too radical and it did it's best at 33 degrees timing as opposed to 35 for the wedge.

I have found that it's not totally immune to pingging. There are other factors here that make this combo different (heavier car, less gear, 4 speed) but you still need to keep this in mind.
