Skyler,

My compression is 10.5:1. I don't think you're being rude but what do you think is wrong?? I check the plugs regularly and they look fine. I'm using the set of gars that came with the car. The guy I bought the car off told me they were 3.73's but I never checked myself. I assumed he knew what he was talking about. Couldn't part of the problem be that I could be letting off the gas before the final MPH line? I set the car up for street use and have mostly 302 parts, unported, unpolished, right out of the box. Plus, I don't have any chip. I own a JMS chip that they burned for me when I needed to get a sticker. Haven't sent it back to them since I put the bigger cam in. Maybe I should?

If your letting off early that could be a big part. I would check the compression on your cylinders it should be around 185 per cylinder. My car runs about 109mph on a 302 w/ the same parts. The extra inches should add another 60hp atleast. You made just need more tuneing. I gained 1.5mph alone adjusting shift points. Just want ya to get the most outta your combo.

OK, sounds good to me. I'll test for compression and get back to ya.

Thanks Skyler
