Just working a set of heads this week that came off of what I believe to be one of the most powerfull naturally aspirated 59 degree head small block Chryslers ever built. I guess the reason I'm posting about it is because of the lack of "trickery" in the motor. I've known the owner for maybe a year now, and talked to him every once in a while and he just sent his heads in for this seasons freshening. Just doing a VJ, milling them and swapping on a new set of Nex Tek springs.

Anyhow... here is the basic combo:

It's a 4.07" bore 340, 4" SCAT 4340 crank, Eagle H beams, Ross off shelf Dome 4" crank pistons. So it's a very basic 416 shortblock with off the shelf parts. No trick ring pack, no Chevy rods, no race block no nothing.

It's right around 13.5:1 compression with a 63 CC chamber. This is a gasoline burning motor.

I don't remember what brand of oil pan is on it, but it is a regular old melling M72HV internal pump and an off the shelf style race pan. So it does'nt have a dry sump etc.

It does have a vacuum pump, Weber belt drive just for steady timing, Mezziere electric water pump, and is driving an alternator.

The cam is a very simple "base roller" design picked by Lazerri at ICH, it's a 279/279 .680"/.680" on a 108 LSA installed at 108. That cam is 197 @ .200", so it's fast but not ultra fast.

It has a INDY 360-3 intake that has been port matched and some plenum work.

Carb is a 1000 Race Demon.

Heads are INDY 360-2 Oval Ports Started life as their 230 CC CNC version. Went to a SB Ford head specialist in Michigan, he put 2.15/1.625 Ferrea's in them, did a VJ, opened up the intake throat for the bigger valve, and sand rolled the ports and chambers.

Using the INDY 440-1 Cast rockers (1.6's), off shelf 3/8" pushrods, no trick double tapers etc. The springs are actually K motions and checked out at anywhere between 220-245 on the seat, 630-660 open. They have two seasons on them.

And a set of 2" Heddman Hustlers....

That's it.... very basic shortblock, basic cam design, and a set of basically off the shelf heads and intake.

Car weighs between 3050-3060 with driver and fuel.

Best of high 5.80's 114 in the 1/8, 9.40's 142 1/4 mile.

Based on the Moroso speed calculator it's making around 670 HP at the flywheel. The dyno we use seems to correlate very closely to the Moroso calc, and so far the most powerfull 59* head motor on it has been a 360-2 CNC 230 416 making 630 on gasoline with a 258/262 roller and 650's on methanol. 9 sec W2 and W5 motor have made 6-0's So his #'s seem to be in line. I talk to alot of people every day about Small Block Mopar engine combos and what they run, and as far as I remember, this is in my eyes the most powerfull NA 59 degree head motor I have heard of. I have not even seen any methanol motors that have made more.

Anyhow, just thought I'd post about this combo, since I have now had the heads in my hands to see what they are like and have the cam card etc. I attached a pic of it.

I really like these -2 230 CNC heads. I think I'm going to buy out the shop's investment in the MP Engine contest motor I'm currently building after the contest is over and yank off the tiny chamber heads that will be on it and put a set of these 230's on it which will knock my compression back down into real world pump gas teritory and I may end up putting that motor in my soon to arrive new '70 SuperBee this Summer to drive. I just have to have a set of these -2's myself, and that motor will be too radical to actually drive on street alot with the contest heads on.

Anyhow.... Don't see 5.80 114 MPH 59 degree SB engine combos every day.
