I want to bore it 0.30 over some head work and a mild cam like pulling 4x4ing cam

 

You need a 5.8 ECU but the motor in my sig will run on an SD computer.

 

Thanks Conanski can u give me a total list of parts .It would be great becouse Iam going to have someone do the moter work for me thankyou

 

I don't have actual part numbers and what you need will depend upon the machine work the block and rotating assembly needs. My block was bored 0.030" over and I used flat top pistons with valve reliefs for about 9:1 compression. The crank was good but some of the rods needed to be resized, after than it took stock size bearings. The cam bearing were also replaced, and I bought high quality rod bolts as well. You'll need the cam and lifters as well. I ported the stock heads myself and had the machine shop do a 3 angle valve job on the stock valves which were all reused. It's hardly worth putting new valves in these heads, if you are going that far pickup a set of used or rebuilt GT40 heads, then you're ahead of the game. Also consider that the World Products windsor heads for example are available for under $1000 brand new for the pair.. with valves and springs, and these out perform all the factory ford heads. It's all too easy to spend a lot of money on the heads at the machine shop, so get prices on replacements before you do anything.

Oh. by the way.. a 351 built like this KILLS the 302.. it's not even close, you'll definitely like this motor.
Do you have a complete EFI 5.8 for the swap? The 5.0 intake, distributor, and oilpan don't fit.. just so you know.
