De-Stroked 454.

What you opinions on a de-stroked 454? Im looking for feedback on my engine plans.
454 2 bolt main block w/ main studs
Eagle 3.75 stroke 4340 crank
Eagle +.25 long rods
10.5 comp. Forged pistons
Brodix Race Rite oval port heads
Solid roller cam ???specs
Team G intake
Reworked 750 Holley DP
Im looking for a motor to run OK on the street, be able to hold its own at the drags and able to turns some RPMs during an occasional open track event.
Please let me know if you think.
Thanks..

Re: De-Stroked 454.

Then you will have a 427. I'd go with a 4 .250 stroke and .250 longer rods if I was going to spend the money. On the street and the dragsrip that would be an animal compared to the 427. Open track I do not know. That 750 carb is to small. Goodluck.

I have a 496 now and it is about like what you mentioned you want yours to run like.

The problem we have here is that we aren't going to be competitive regardless b/c our motors are do all things pretty good, but do no one thing great like a dedicated motor will do.

Drag cars need high rpm drag motors, a cruiser needs a fuel eff. motor so you don't break the bank cruising and a track/road course or an auto-cross car needs one that makes power everywhere and that can wind up AND down fast.

See what I mean..

I built mine for what I call, max. midrange grunt which is just where I figure a multi-purpose motor needs to produce MOST of it's power the most eff. way it can.

I am right at 9.8 to 1 CR. so I can burn good pump gas and have installed a good old CC 282S solid cam that in my combination , (per D2K), produces right at 550 hp at 5500 rpm and 580 t at 4500 rpm for TO ME, great midrange GRUNT!

I call my motor, my great big, "tow-truck" motor b/c I figure it can be used to pull a 30' horse trailer in a Dualie if I ever have to part with it!

One motor that will come close to what you want to do is like this;

4.6" b x 3.76" s = 500"! It will wind up like a Z-28 motor AND b/c of it's shear size will have plenty of grunt, imho.. Just make sure you have a GOOD/strong high rpm rotating assembly in her is all...

Take your pick and have fun..
