Default 90 363 Fox vs 98 Z

Raced my buddies fox the other day. He has a 5 speed 90 GT with a stroked 363. My car is H/C/I M6 98 Z.

His builder said the car made 370 on a dyno jet off the spray. My car made 406 on a mustang dyno with the cutout closed and an ls1 intake. I have a new intake now but have not dynoed it since. I would guess we are around the same weight because he has subs and a cage while I have some weight reduction mods.

We made 3 runs and the mustang walked me all 3 runs. He had a good steady pull on me. Started at 40 and by the end of forth he had maybe a car and a half on me (127 mph). I started started closing the gap at the top of forth but we were already going fast so there was no point.


He says he didn't spray me until the last run but his pulls were all the same on me. I also saw him smile when he purged the motor (heard it) on the first run. He admits I have him motor only, but only admits to spraying the last race.

I have no idea on how big of a shot he is running.

Nice runs! Those 351-powered Fox's can be nasty.

OP he sprayed you all 3 runs no doubt about it. If all 3 runs looked exactly the same then he must've. I'm willing to bet that he had a 100 shot. Make him pull the bottle out and run them again to see where you both stand. Although you could sneak yourself a lil shot on there then lie to him and turn the tables.

I think its a 100 shot as well. He admits my car will beat him NA and he wont take out the bottle cause hes afraid of how bad it will be lol.

I wanna run with out the spray just to see the motor to motor. I still have the stock tb, MAF on my Pro Flo and my cut out was closed. I have around 30 rwhp hiding in this combo still. I would think with the 90mm upgrade and the cutout open (worth 16rwhp old set up) it would be a close race. It was a really good race Ill admit that. I wanna up grade the tb, tune with the cut out open and have another go at it before he pulls the bottle.

I have a manual cut out so I didn't feel like crawling under the car. I just got my intake finished up and didn't have the extra funds to get the 90mm set up right away.

Car is fully tuned, just not optimal mods yet.

It's not a 351, it's a 302.

I dont know if it is an aftermarket block or not. Ive been reading up on 363s and they can be down right nasty.

I dont know the specs on the motor, wish I did

That mustang guy is at just over 1hp per cubic inch that's pretty sad for a stroked,heads,cam etc.

Hmm. I would imagine it's an aftermarket (maybe Dart???) block with a 4.125" bore and taller 8.2-8.7" deck height? Most likely running Wedge-style heads. Interesting, never ran into anyone with that combo.

Yeah, that combo should definitely make more power once everything is optimized. That cam is no joke. Seen M6 cars pull numbers close to that with just the cam + full bolt-ons (stock 241's).

It definately is an aftermarket blocked 8.2 (aka 302 based). 351 is 9.5"

363 IMO is a funny build that isn't for everyone. Sounds like guy would have been better off with a 408 or like.

Agreed. 408 would have made more sense IMO.

In fairness to him he bought the car how it sits. Car is loaded like a damn summit catalog. The 370 rwhp number could have been a lie to me from the builder. Ill find out more info tonight on it.
