Nice man, you should definitely notice difference between those garbage E6s and the ported E7s. Did thumper do the porting?

Also, I hate to be one of those guys that points something out, but I think either the backspacing on those rear wheels is way off, or you have the wrong length axles back there. Easily fixable. Car looks awesome otherwise!

I bought them ported, guy said they were done by a shop in TX... When i got the heads i droped em off at the shop and the guy said they have been lightly ported and he was going to do more and open up the Bowels? in side more... So they should flow some where close to Thumper's when they get done...

Those tires and rims came with the car... They do stick out some... I guess cause the guy wanted to run a bigger tire.. there are 295's on the back... I plan on selling the rims soon...

How much did they hit you for the headwork?

 

[Jaswir]

$350

comparing the size of them ports compared to gt40p heads there tiny. you could of got gt40p heads for less then that and ported them. why didnt you go that route?

 

[Jaswir]

cause i have flat top pistions... and GT40 heads will cause PTV problems...

These heads will outflow GT40's

Those heads will outflow unported GT40s. But I think some guys are forgetting you're stepping up from E6s. Sure, you could have gotten GT40s, but you also could have gotten GT40Xs, Twisted Wedges, AFR 165s, AFR 185s, Canfield 195s, or AFR CNC'd 225s. Those ported E7s will be a nice step up from E6s and should pull fine for a budget build.

I like the 85/86 mustangs!

I agree with notchbacklx, you ARE upgrading from e6's. But still you really didnt get a bad deal, because you have a set of fresh heads, with a small port job, for a decent price. If you would gone the iron gt40 route you woulda paid that much for a set of dirty unported heads, that would probably need valvetrain work.

And Ryan if you read up on what it takes to port these heads you will realize MOSTLY all of the work is inside the heads and around the bowls and valves, just because the ports arent huge doesnt mean they cant outflow a set of gt40's.

lil update its almost back togeather! I just need to put the upper intake on and hook up a couple lines!

Man, what a bad-ass looking car! Congrats on the project!

 

[Cobra912]

excellent idea, should really wake the car up. I wanted to swap out my 86 heads too, but I went crazy and pulled the whole motor! Now I have a 331 and a blower..........wish I went the easy 350 dollar route.........lol............ keep us posted!

Nice man! Hurry up and get the car off the grass!! I've seen what parking a car over grass for a while can do to the underside

Have you checked piston to valve clearance? Some guys get away with running E7s, but its still worth looking. '86 pistons won't accept a lot of heads/cams since they don't have notches.

 

[Jaswir]

yea it clears, i kept the stock cam just to besafe... planning on running nitrious soon then i guess when i get bored the motor is going to be stroked

A better question would be, why didnt he just dish out another 350 and get a set of used twisted wedge heads?
