Block and internals should be the same as a stang. You'll definitely want to change the cam. If you're sending the heads to Thumper, you might as well throw in a stroker kit.

yeah cause that only doubles the money he's spending[&:]

I paid $500 for a 2000 model explorer motor with 60k miles on it. So you got one hell of a deal.

The explorer motor has different pistons giving it only 9:1 compression with the 58cc chamber GT40P heads. The pistons are also hypertechnic not forged like the 5.0HO pistons.

The pistons aren't what changes the compression...the heads have smaller chambers. The pistons are the same hyper pistons used in 93+ stangs.

Excuse you??? Did you ever think that maybe the pistons in the exploder motors had a larger dish for better quench??? thus reducing the compression ratio?


or is that too difficult?

ovalracer98

If the pistons were not different then dont you think that just maybe that the compression would be higher than 8.8:1-9:1 with a 58cc chamber on explorer block?? think about it... If you were to take a 58cc head and put it on 5.0HO block you would have around 9.5:1 ratio. Pistons have to be different

No, I didn't think about that or I probably wouldn't have posted what I did....thanks for correcting me, though.

ovalracer, that's something I hadn't thought about...thanks for the correct (and detailed) explanation.
