I'm still scratching my head as to why I pulled out a perfectly good 341" (3.91" 318 factory roller block with an MP 3.55" 4340 stroke) to put in the 414, I'll bet this puppy made about 440hp (PLENTY!!) with a 236/240@.050 Hyd Roller and stock E-heads.






I've been doing the same thing.....I thought you were crazy to dump that motor

it's not like Rocky needed more TORK!

No need to be sarcastic Carlos. Besides your 360 has a bore of 4.00" you would need to sleeve it to go down to 3,90. Heck even the 318 is just 3,91" std bore.

In the end, the extra 0,040" overbore you are thinking of will yield just an extra 8 inches on a 4" stroke crank motor.

That should amount to an extra 10hp - 15hp on your w2 motor at the most. Thats if your cylinder walls are nice and thick at the thrust side.

If you think that will give you the extra edge that you need to go win races, then go for it.

Well after testing yesterday morning I was able to try a few things that may be of some interest to some. The air quality was very good yesterday with the correction factor hovering at about 1.00 which is rare. Usually the STP correction factor is anywhere from 1.025-1.05
Anyways I started with the four hole Wilson and power was 427-428 @ 5900-6000rpm with torque in the 435-437 ft/lb range with excellent consistency from pull to pull. Jetting wound up @ 80-85 with the customers 750 Proform. Timing was 35 total and not changed. Just to satisfy my curiosity I removed the electric water pump and installed the customer's water pump with a single v belt. Torque was unaffected but power was now down about 7-8 hp at the very top of the RPM range. The last 2 tests were to verify power output minus the spacer and electric water pump. Torque was solidly up into the 440 lb/ft range with horsepower unaffected and still hanging @ 420-421. The no spacer pull's averages were actually 1 hp and 1.5 ft/lbs better over the entire 3500 rpm-6000 rpm span. I do not have a scanner at the shop so maybe I can scan and post the sheets tonight. I will have another stock stroke 360 with ported EQ Magnums on the dyno soon-it will be very interesting to see how it compares. J.Rob

1.2 ft-lb/cid is pretty nice for a simple, low tech street motor...

I think this has been a very interesting read. And, an impressive motor. I have new respect for that Voodoo grind, I'll tell ya! Like a good book, can't wait to see what the EQ-headed 360 is all about, since I'm going that way with a 408 soon.

This "street" motor, with the right converter and traction would be deep in the 11's while able to be driven both ways...

Thanks RAMM

Thanks for the thanks. I am quite hopeful that the EQ headed 367 will make quite a bit more steam than this mild example-but--- you never really know until you do it. Sometimes less really is more. J.Rob

Depending on how you prepped the EQ heads and camshaft, I think they may surpirse some people here.

I would agree. Although we're not done with them, the EQ's I have flow VERY WELL below .550 and very near the RHS heads on our bracket car above .550.

So how do you think this engine would have done with the 268/276 voodoo cam?

Howdy I know this is an old post but it's appeared on my computor at the perfect time. I have a vintage front engine dragster for a bit of 1/8th mile fun and I just lost lobes off my old ST21 RB camshaft and subsequent damage. My 360 is identical to this engine - valves heads etc except I have KB 190 pistons so it has a little more compression. I put the lower set of torque numbers in to a decent racing simulator and this basic lazy combo will run 5.60's in my car. Thanks you've made Cam selection easy for me. Cheers

Impressive! I have almost the exact same built going in to a 2100 lb street rod with 3.55 gearing - 727 trans with 3000 stall convertor. Can I get it in the 12's?
