4.0 Re-Build

[JMan689]

Alright this summer I'm finally going to rebuild/build a 4.0 to drop in the X.

I'm thinking:
410 Comp cam
Headers
Throttle Mod
Underdrive Pulleys

I already have a new coil, plugs and wires laying around in my closet.

Anything else i should be going for? Looking to make this a relatively cheap build/rebuild. Thoughts on a set of headers? Should i bother porting the heads? Anything specific other than the cam i should really spend money on?

if you want 10:1 you have to change the heads to 95tm,i suggest engine quest only people that make true 95tm heads.if you are wanting a cheap build forget about porting,if you do any porting do it to the lower intake manifold.if you want 10:1 go with the 422 cam it will work better with the compression,but that means dual 988 springs.also your want to run delta cams rockers and pushrods and SI one piece ss valves.use the high flow oil pump by millings,it helps alot.i run pace setter headers,they are cheap but make sure you get ceramic ones or properly paint and bake them with ceramic paint.underdrive pulleys,throttle body mod or bbk and e fan should be on that list somewhere also.

Alright so scratch the compression and porting then. Last i remember reading the e fans weren't cooling enough for wheeling applications so i don't want to go that route.
