Edelbrock Performer intake

600 cfm Holley

Camshaft @ 0.050
214 degrees intake
224 degrees Exaust
518" Intake
544" Exaust
112 l/c

Small tube headers 1 5/8"

Thanks for your replies in advance

This is very close to the motor I built and have in my 1965 F100, Very strong mid range a real torque monster. If you have not yet purchased. I would get the Weiand Stealth manifold be sure, if you go with a dual exhaust set, up you use an x-pipe or crossover

I'm with Chilly on this one. 1 5/8 headers are too small. You probably can't even find headers that size. 1 3/4 headers are very common though and will work good for your application. Just make sure that the tubes are long, at least 40", and run a long collector, approx 20" - 25", between the header and the H or X pipe. That goes a long ways toward boosting torque in the 2300 - 3000 RPM range. Personally, I'd probably run a little less cam, unless you have a tow vehicle with very low gears that will be revving at least 3000 RPM during cruise conditions. Crane's Powermax H-260-2 (204-216 .487-.518 112l/s) makes awesome torque from 2400 to 3600 RPM. The Performer intake is perfect, but I'd go with a 750 vac/sec carb. It'll gain you some horsepower but won't cost you any low end torque on that big engine. Just my thoughts on your combo.

Thanks for all your input!

You guys are right, I can only get headers in 1 3/4" diameter.

I used a combination close to yours and was very happy with the outcome.Holley 450 or 600 cfm vacumn secondary carb,Performer intake(port matched),E3TE heads with extensive exhaust tract work with 1.71" valve,CompCams 4X4 Extreme cam(505/255/26
with correct springs,9.1:1cr,1 7/8" headers,C6,3.25 axle ratio.This combo will not only pull a trailer apart,it will also give most "street cars" a run for the money!...Livermore Dave.
Cam specs .505"/255/268...how did that silly red dot get there?

I've got the Crane cam that Mach1Morgan described in his post in my 460, and it makes awesome torque, I'd say at least 500lb/ft at 2000rpm. I've also got an Edelbrock 750, Performer intake, stock heads, around 9.5:1 compression, Thorley headers, and 2.5" dual exhaust with Dynomax Super Turbo Hemis. I'd say if you have the money, go with a Tri-Y type header like the Thorleys, they're supposed to make excellent torque compared to normal headers.

There's an 8% grade that's 6 miles long that I have to drive up every day to go to college, and my Broco doesn't have any problem pulling it 60mph at 2000rpm (in overdrive). I think that's pretty decent low-end torque, since most new rigs I've ridden in can't pull that grade at that low of RPM.

Earlier I failed to mention I run a 9-1 static CR. For a towing application I would not build with any higher than 9-1. Also I would choose the Comp Cams Extreem 4x4 cam #34-235-4 210-218 .505 lift Too much compression on truck engines will cause overheating and may lead to engine failure. You will be well pleased with a 9-1 460. The recipe Livermore Dave shared sounds like a winner!
