I have the E-303 cam and Crane's 1.7s in my car. Crane made the 1.7s for the 1993 Cobra engine. I have ported and polished "Powerheads", which are stock E7TE heads, but worked over with bigger valves, etc. I used the stock pistons. Clearance is not an issue. Not sure about the GT40 heads, though.

I guess I didn't really answer your question, did I? Post this in the "Ask Levy Racing" forum. You'll get an answer for sure.

I am using Scorpion 1.72 roller rockers and the E cam with my 347 with Twisted Wedge heads. I have not installed the engine in the car. I had to install longer push rods to make the rockers work. I have plenty of clearance with the pistons. No estimate on the rwhp.

yes...you'll have .529 lift where .530 is the max with the stock pistons...of course it wouldn't hurt to clay it...should make 330-340 fwhp...it's kinda my set up but when i went forged pistons i fly cut them in case i wanted to upgrade later...i have the y Al heads...you may need to up the injectors too

my best guess with the "E" cam is .512 lift if the rockers are 1.7.1 or .516 if the rockers are 1.72.1..........

We have the GT40P heads, E cam and Ford 1.7 rockers with a carb.

No problems, its 280 RWHP and 300 RWTQ.
