Trick Flow 500ci RESULTS Are In! PART 2

[MRL Performance]

Ok so here is the "Other" 500 i had in the shop with those pesky little Trick Flow heads. Almost the same build as this one http://www.forabodiesonly.com/mopar/showthread.php?t=336635 with a few changes.

440 RB block 4.350 bore
4.150 stroke
7.100 rod
10.5 to 1 compression
MRL Custom HR cam High 230's duration .580's lift

Just about everything else is the same. Same heads, intake, carb, fuel. headers, dyno..... all the same. Now I knew I was going to give up a tad bit of torque with the lower compression, slightly more duration and longer rod, with hopes of make more top end HP. And wouldnt you know it, thats exactly what happen LOL

TQ peak was 670TQ at 3800-4000 with 600+ from >3000rpm to 5450rpm

HP peak was 628HP at 5400rpm with 600+HP from 4900rpm on up.

So we gave up 5TQ peak for a longer torque curve and gained 20HP. Win Win.

Cooooooooooooooooooool!

I wonder what my 440 with 8.7cr and these heads will make.

I want to see one with more compression and a big solid roller.

I'd love to see some 1/4mi MPH numbers from these Trick Flow headed motors. Anyone have any yet???

Same thing I'm thinking. I'm hell bent on keeping a flat hood and an air cleaner on my Gold Duster street car. I'd love to see what this engine does with 11.5 or 12 to 1, a good solid roller and a ported Torker II or RPM so it fits.

At 12:1 you'll be over 700 hp. My 470 is making 675 hp and 630 ft-lbs of torque on pump gas with 10.5 compression. The extra compression would move it up to the 725 range.

I just finished up a 500 Low deck with 10.9 comp, solid roller on pump gas 650/650. That was with RPM heads flowing about 30cfm less than the TF heads. If it had the TF it would be over 700 for sure.

Thanks

I assume you used a big single plane like an M1. How much power do you estimate a low intake like a Torker II or RPM would cost on it?

thats awesome !

I used a M1 4500 intake which isn't really all that tall of an intake. I don't know much about the Torker II intake. The RPM intake would cost a bunch of power. I wouldn't run a dual plane on a 700 hp engine. The AF ratio variations from cylinder to cylinder could be fatal at that power level.
