Let's play guess the hp & Trq

Post  jones on December 9th 2014, 4:24 pm

Kick's and giggles let's play guess the hp for this engine combo.

521cu
Ported scj cylinder heads
Ported Victor 4500 intake
10:1 compression ratio
1050 4700 Quick fuel carb from Phillip
Edelbrock water pump
Crower SS rocker arms
Ford racing  M-6250-521 solid roller camshaft
I hope to have the engine dyno'd before I bring it home from KY!

This engine is based on the old Ford Motorsports 521 crate engine except for the better flowing heads and intake. If I'm not mistake the crate engine was rated some where around 650hp.

Ford rated the 10:1 CR 521 at 580 hp.

The camshaft is quite mild I would guess 630 or 640 HP with better flowing heads (probably won't see any gains with a ported Victor intake
on a 6000 rpm max engine).

Sounds like you already know what it will make?

I didn't know that, I guess I didn't do much research. The hope is that the 521 camshaft will be mild enough not to cause the valve train to eat it's self.

J607 is the formula that is relative to this post. I'm not aware of who uses the 1349 besides maybe the o.e.m.s. production engines.

OK different standards show different HP, but some are throwing out fantasy HP numbers for a 10:1 521 and a very small solid roller cam.
750hp? really? 650 hp would not be a piece of cake with the OP parts list.

It's not like I have had a million responses to this thread! The motor can always have another camshaft made for it.

Thats why I didn't want nothing to do with building this engine. I gave the builder an idea of what I wanted to do and let him have free rein! No HP goals was ever said.

Ps of course now that the build is all done but running I'm kinda curious as to how much it might make. The dyno will be strictly for trying on carbs, rough tune, real-in and torque converter selection.

The typical 521 SCJ crate engine with an xr292 cam swap typically does push 700hp, fact not fantasy.

Like Jones just said, this project will be done per the orginal spec. The short block was available because of my own a.d.d. ......an unfinished project for a vintage jetboat deal.

Any way....I do not know why any of us ever dyno any engine....every mofo on the internet already knows what it's gonna make. Laughing

The dyno don't lie.

I'm looking at an artical from Super Rod published in July 2002 702hp and 725lb on Westech's dyno. No reason not to believe it. Its on comp cams website too.

I agree either that or go buy a desk top dyno and you can plug in some bs and it will tell you exactly what you have

there is a guy in the next town a buddy and I went to the parts house to get something this guy was telling me he is building a 1000hp 350 chevy and it will be a street car he knows this cuz he tallied up all the parts he was going to use and the advertised hp they all supposedly make when adding to an engine...
