351w swap

I am swaping the 302 out of my 2wd 76 f-100 for a rebult 351w.

I need to know what headers to use, I am not having luck.

Also I would like to know what flexplate that I would need. (I am assuming a 28 oz. but don't know how many teeth or size of torque converter)

I currently have a c4 auto. I plan on rebuilding the tranny or getting a rebulit one from advance auto. It has a dipstick coming out of the body not the pan.

The engine is about done

it has 9:1 compression 0.030 overbored everything shot peened and re machined and has been dynamically balanced. the heads are late model that are slightly ported with roller rockers. and a comp cams x-treem 4x4 cam.

I plan on runnig a performer intake with a holly 600cfm carb.
and a mallory dual point dist.

any other suggestions?

thanks,

john

I used 302 headers for same swap in my 77. Your 302 flexplate will work with 351.

I thought that the 302 flexplate has a 50 oz weight and that 351w's require a 28 oz weight.

thanks,

351w swap

302 counterweight changed around 82, previous to that 351 & 302 had the same counterweight.

I used MAC shorty headers for a Mustang when I put my 351W in my 79, you can see some pictures in my gallery.
