As they say in talk radio "long time listner first time caller" I have come here and hope to drink from the "well of knwoledge". I'm been talking with a another board member about my Ford set up and I'll throw it out here and see what the well throws back. Car :1964 Ranchero, Motor: 260, Trans: T-10 4 speed, Rearend: 3:25 peg leg. The car will be a mild street strip car and I want to make a cam change and I've been reading all posts and I think I'll go with the 270S Comp cam ,with Comp Magnum Steel Roller Rocker arms. Also bolt on a Edelbrock Air Gap RPM intake with a 600 Holley, the engine is fresh and ready to go and I have another fresh 260 as a back up. The car (truck ?)has Hooker Headers with dual exhaust. My question is since I'm doing a cam swap would I gain anything from taking off the heads and installing larger intake valves (1.94)in the stock 260 heads or invest in some better heads ?? Thanks !!

If maintaining an outward stock appearance is not an issue I would say the best use of money you could make would be a 302 short block. I don't know if it is possible, I am more of a FE / 460 guy, but could you use a 302 crank, rods, and pistons in the blocks you already have? An extra 40 cubes will really perk things up, and stroking it to 331 or 347 would REALLY get things jumping. No substitue for cubes.

260 heads really stink so I would not was any effort on trying to improve them. Better to look into some aftermarket or done up 289-351W heads for a good price.
Oh by the way, welcome to M&M

i have a set of 69 351W big valve heads and a set of 68 289 64cc heads. you can have em if ya want em. the both need to be gone over. the 351 heads are really rough.
As for the 260 heads, i have a set of those too. I use em as wheel chocks.

It'd be wasting money to try and do the 260. Better off to get a 5 bolt 63-65 289 block and build that up. You could use a whole 5.0L if you used a scattershield or a bellhousing with the narrow trans. case bolt pattern.

Thanks for the reply guys . The 260 is what I have to work with and both motors are 5 bolt blocks so when they are used up then I'll switch over to a 302 set up .I scored a 5 bolt C-4 bellhousing off ebay so I could go automatic trans if I wanted too. Now my local wrecking yard is having a half off sell this weekend there is a few 289 and 5.0 motors (85 and a 86 5.0's) out there which heads would work best on the motor ? The advise about the 260 heads is right on. It would like bolting a 265 chevy heads on a 350 motor it'll work but your not gaining anything. And Slow65 thanks for the offer but it would be cheaper if I went to my local boneyard (I'm in California) So how about the heads guys ?? Thanks Rich T.

whatever heads have the smallest chambers. This thing will be a real dog if you lowered the compression.

I think its throwing good money after bad to stay with the 260 when 289's and 302's are common... but to each his own.

By the way, larger valves aren't going to clear the cylinder walls of the smaller bore 260. Stick with 1.78" and 1.45's
