![]() your combos is similair to mine, same crappy gears too.
My car has the front swaybar removed, and i run it hard to get in the 12's, i hate to say it dude, but a 302 shouldnt be bored over more than .030, maybe .40 at most, just make sure you got a good cooling system in that thing. btw, you really dont need a 3" h-pipe. also with the 4 banger springs and skinnys up front, i can see 12's easy, get gears and you can go faster.

![]() .060 over is on the ragged edge but it will be ok. My 351w is .060 and that's as far as it can go.
Anyhow, I would go with the 4:10's with your 5 speed. I would guess that your current setup will get you mid 13's and your future mods should get you in the high 12's.

![]() What tires you running? that has alot to do with it too. also that performer rpm intake you car will loose some bottom end torque and with those 3.27 gears your not gonna be revving to high at the end unless you go through in 3rd gear

![]() Easy 12's.
By the way boring a 302 60 over is very common and popular. You wont have any issues. I know many people running 310's

Have you ever raced at the track before? That's going to make a big difference also. If it's going to be your first time out then I would say mid 13's for sure.

![]() Yeah i agree about the tires too. im gonna have the BFGoodrich g-force t/a drag radials. probably 275/50/15's. yeah i know those gears suck but i plan on getting either 3.73's or 4.10's sometime in the next few months. no i've never accually raced at a track before. i figured my lack of track experience would effect the outcome, but im gonna do my best. haha

![]() My friend just got some of those new g-force drags, 275/40/17's
I wonder if they are better than the old style bfg dr's? I never saw 12's with drag radials, I think I could do it now though since i figured out how much psi those things need to launch, those tires are just too pricey considering how long they last. ![]()

![]() Your current combination should make over 300hp without a problem, if it's tuned. I hope you have valvesprings that are better than the OEM type on those GT-40P's. The OEM springs are a little weak and good for only up to .500 lift. Your E-303/1.7 combo will have .529. Also, GT40P heads lose flow after .500, stock so until you do some headwork, don't expect to see much of an advantage from the 1.7 rockers.
With the 3.27 gears, the car will be capable of 12s, whether you can drive it there or not is another question entirely. The day a decent head/cam/intake 5spd fox notch can't get better than mid 13's is the day it needs a tune badly. It should be capable of running a mid 13 with a couple of bolt ons. |

![]() He's still going to need traction plus the fact that it's going to be his first time to the track.
Poor traction+novice driver=poor E.T's

![]() I hate to see this question. It is a guessing game for all. 10 people can build that same combo, and you will get ten differant ETs and speeds. From 14s to almost 11s. We go through the same stuff with the 4 wheelers. I have ported 40 sets of cylinders and only 2 ran what and what. Mine was the fastest, 7.08 at 96.4mph in the 1/8th. I even swithched cylinders with a few fellas who thought that I did a better job on my own stuff. When the swapping was done I ran the same and so did they. Put your stuff together and we will help you achieve your goals. You will love it and so will the mustangworks family, thats why we are all here, good luck.

![]() I see your point and I understand how you answered it but usually when someone asks what their combo will run, that's usually the number they expect to run.
Then, when they don't run the numbers they are looking for, they rack their brains trying to figure out what's wrong with the engine setup.(regardless of driving abilities) Maybe the question should have been "What do you think this combo can run? I guess the bottom line is that the setup is capable of 12's but he's only going to see 13's with his experience and lack of traction.
