The build:
'84 360 block .060" (bores would not cleanup at anything less)
Eagle steel crank 3.58" (stock stroke)
Scat I-beams (stock length)
Icon Forged flat tops 4.06" @ zero deck 1/16" ring pack Napier 2nd
Felpro 519 SD gaskets
Comp Cam 294 S w Hughes EDM lifters
Heavily ported EQ Magnums 300cfm @ .600"+
T&D 1.5/1.5 shaft rockers
Eddy 2815 SV intake
Holley 950 HP Ultra
1 5/8"-1 3/4" dyno headers with Magnaflow muffs.

So here we have a 10.8 comp stock stroke 360 with a low lift solid lifter camshaft I bought at a garage sale for $60 with heads that are iron. Admittedly the trickest parts of the build are the rockers and induction. Nevertheless I was pleasantly surprised with the outcome. J.Rob

Here's the results. This was the final test last Friday. I turned it 7250 rpm many times just to see the shape of the curve. This engine is the happiest revving 360 I've ever built. This would certainly be happier in a more strip oriented ride I would imagine.

Yes it's a little rich--I ran out of gas and time on Friday. There may be more. J.Rob

Impressive #'s. Big time port work to get 300 cfm from those heads. Nice combo. Torque curve nice and broad - and not too far up in to the rpm range.

Fastest 300

Thanks guys. Yes the heads are worked extensively as is the intake manifold. I don't find the torque to be all that impressive. I tested at 4000 rpm and it produced 410-415 ft/lbs. However what is impressive is the little .507" net lift after .018" lash cam made even what it did. I was expecting much less to be honest maybe 485-500 hp max. J.Rob

Very Nice!

Would think a smaller manifold like an Air Gap would broaden the torque curve (higher average) than the SV which (using conventional thought anyway) would skew the power upstairs at the expense of the upper bottom/midrange.

Very Impressive overall power...especially considering the smallish cam.

Might you share the rest of the cam specs?

Thanks!

Very impressive!

I bet a set of 1.6 rockers would add quite a bit, get it more into the flow zone of the heads and slightly improve the PR geometry

I can't speak for these heads, but I doubt it. Velocity seems to be a key part of the Magnum head. When I fist looked a set of RHS ports, I thought, "NO WAY will these flow." I was wrong...end of story.

Very impressive numbers...can't wait to see what it does in the car.

Jeez I hope my new MCH CNC Eddy's don't want to turn that much rpm...my cast crank hates me enough as it is...lol
