It is 383   4.06 x 3.7

What cubic inch is it?

Here is a video from a couple years ago of the engine I am running in EMC.. I ran out of tuning time at the dyno session and just was content with a 500 hp number.. I think there is another 25 or 30 horse in it with some careful tuning.. The cam is actually a little too big for the rpm range of the contest.. I am going to try advancing the cam some to get the torque peak down a couple hundred rpm, I will also try a manifold with long straight runners and Tri Y header to pump up the mid range torque. That torque number needs to be close to 500 ft/lb.

Sorry for the questionable videography

This year starts to be very interesting.
Especially the Lincoln Y.

Jerry christenson and I are both on the alternate list.

There are two Poly motors.
One is pretty much an early hemi with poly heads, which has little in common with later LA engines (273, 318, 340, 360).
The other Poly has little to do with the early hemi and does have more in common with the LA engines.  These 318s will be the later variant.

Isn't the Poly motor a Hemi block without the heads?

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Chuck the poly is kind of a semi hemi. It has canted valves but a single rocker shaft. They were introduced in Plymouths. They were cheaper to mfg that the Gen 1 hemi and lighter as well. Their heads flow pretty well. They will make some good numbers.  The EMC has all hemis lumped together gen 1 2 and 3 in one class.  A few yrs ago a Gen 1 hemi finished 2nd or 3rd overall so they have some big potential..If they were allowed in vintage they would be very tough to beat.

6 engines is a full field..

I wish they had allowed the Hemi.  If they do it again next year, I think they should use a slightly later date, and simply keep all mainstream engines out of it, so no FE Fords, no SBC, no mall block Mopar, and allow the early Hemi, if only to see how the other engines compare to the legend - I bet the results would be surprising.

Can any other participants be added at this point or are these the only 6 that there will be?
