Have you ever ran your rig in the 1/4 mile yet?

No i havent ran my car with the 4:10s yet, but last year with street tires and stock gear i was running 13's whats your 1/4 mile time

Low 11's bit i had a Great 0-60 ft and a 100 shot along with a centerforce stage 3 clutch and drag susp and slicks.. With out the bottle and slicks I ran a 12.28 which is pretty good for a rebuilt 302 bored .30 thousands, the balencing and blut printing helped alot to.

I eat all the little honda cars in my town for lunch from a dig or rolling, But then again i dont have a fuel cut off or rev limiter..

Ive been known to float valves..hehe

Do you have all the parts yet or is that what you want to buy? I have an almost identical setup except im running Twisted Wedge heads, the intake is a GT-40(same thing), 1.7's, 24# and a 150 shot.

Mine isnt together yet but I wish I would have done a couple of things different. I don't really like my intake, I have a 65mm TB and I should have done a 70mm, and I def. will be changing the cam. If I were you I would go with a Trick Flow intake and a custom grind cam. I would do longtubes too.

And +1 on the balancing. the motor will run better and last longer

i think i might go with the 65mm tb and egr spacer. as for the bottom end ill have my crank shaved and balanced. For heads im thinking bigger valves, ported and polished heads. should i go with 1.6 or 1.7 roller rockers? which would work best with the E303 cam and the 351w heads?

Get the entire rotating assembly balanced, not just the crank.

Rods, pistons and crank.

[patwrecked]

go to 1.7 rockers. trick flow upper and lower.

[Speedstang302]

what kinda rockers you plan on going w/?...i say harland sharp, they've been around for the longest and i think they are the best for power and reliability...and obviously go w/ the 1.7s, thats what i have 1.7's w/ lunatti brackett racing cam, completely race rebuilt GT40 head, trick flow upper and lower and bbk 70mm, and longtubes and h pipe....40 series tooooo....

[89LX347]

actually arent the 1.6 roller rockers better?look at the forum at the top about dyno myths..maybe i read wrong..and id just stick a carb on the thing and not have to worry about all the EFI stuff..and id probably go with the edelbrock victor junior heads..and get an anderson custom grind cam shaft they are the best at it

[Tony_90fox]

I have a similar setup just waiting on a few more things to get here...

I have:

Mac longtubes
Mac off road H pipe
Flowmaster 40s dumped
u/d pullies
4:10s
73mm C&L MAF
65mm TB
24 pound injectors
Ported cobra upper/lower intake
Ported GT40 heads
FMS B303 cam
Crane 1.7 RRs
Mickey T slicks
Transgo shift kit
2200-2800 converter
Comp cams valve springs

still need adustable fuel pressure regulator, a/c delete, short belt, trans cooler

Personally, i would go with the B cam because it pulls more up top (so i have heard)..Not that sound is everything, but a FMS B cam with 1.7 RRs is going to lope good and sound GREAT with my current exhaust.

Just need to get a few more parts and find time to install it. I have heard everything from 260-315 to the wheels, so i am not going to guess on anything. But my mustang now with exhaust, pullies and filter pulled 200 RWHP and 290 TQ through an AOD so i think it will do well with the above mods.

Good luck with your setup.
