I was recently reading in Car Craft (Dec. 06, Pg 48, Make More Horsepower) about the advantages of a 30 degree back cut on both In. and Ex valves, Especially on Ford heads. Granted, this was on an earlier set of heads, but none the less impressive. Furthermore the Ford section ended with "Based on these results, we'll never build another mild small block Ford without back cutting the valves".

It shows the actual flow results at 0.100 - 0.600 valve lifts, worth researching.

yes, unless you have 3.43 gears or higher and like to rev it to the max rpm often, get rid of that cam and use the one below.

in addition to back cutting the valves, port the exhaust or at least blend the bowls a little.

try that intake with and without a 1" spacer.

Map out your ignition advance curve, depending on where it is now, a quicker curve has the potential to feel like you added an extra cylinder on the street.

I'd also look at gears, tranny and converter if you haven't yet. A hard shifting box with a little more torque multiplication is fun and gears of course make all the difference, especially if you run any tire bigger than the truck came with

ON EDIT - Why the cam recommendation above? The cams are nearly identical at 218 @ .050, my opinion is you'd likely not be able to tell the difference between the two. 268/218 I 268/218 E 110 on 106 for one 262/118 an 270/224 110 LSA on 106, within 2 degrees of advertised overlap using .006 or .050 numbers. Not significant and maybe even indistinguishable in my opinion

dlfulp . . isn't this going in your truck that has the 3.50 gears and 27" tall tires?

You didn't say what you were doing with the truck? Is it a 4X4 off roader or a two wheel drive street machine? What trans are you running?

The carb is too small.
