how do ya like them apples

old 305 4bbl "GOT R DONE"

 

Dam...those are awesome times! Congrats!

 

Sweet!

 

Yes, very nice times. BUT just think what it would have run if you had a 350 in it.

 

Do you think you could have done that if you were still running a TBI?

 

thats alot of stall

what gears in the back ?


oh, and what are you planning next ?

 

Until you run into a good ole 12 second 350, that is.... j/k! Have you considered a single plane/650-cfm set up?

 

i thought about getting the S/R World Product heads for the 305 and going up to a 650 holley

the rear has 3.42 with an auburn pro series posi trac

i dont think there is an all motor 305 running in the 12s yet is it??

i figure with the head swap and the three piece pulley set and 650 it should turn a 13.40??

the mods now pushed it barely into the 13s but i figure if i do the head swap then i could put a chigger bigger cam in it too so maybe, just maybe i can put the ole 305 into the 12s at 100+ mph

wouldnt that be some shiznik

 

When Peston Smith 'first' built up his 85 Iroc (305-TPI), he ran mid to high 10's running a Vortech blower. I really don't know what he ran naturally aspirated with that 305, but 12's would honestly not surprise me....

 

Damn dude....right on! 305's UNITE!!!!!!!

 

not bad for a 305!

hopefully mine will be there shortly... since im selling my GN, alls i have left to play with is my old LG4 Z28. 14s shouldnt be too far away for me

one thing i would change on your setup is those flowtech headers. 1.5" primaries are probably too small for the power youll be producing with the new heads. id at least step up to something like 1 5/8" hedman LTs or something

 

Yes he could. He was pretty close before he switched to carb. TBI is fuel limited rather than air limited and is at the mercy of the chip tuning skills of the owner.

Great numbers!

 

Seems like a lot of work and effort to crack a high 13. Should have gone with a 5.0 Mustang, bolted on some gears, and ET Streets and gone 13.9s!









Very nice times for the little 305. We had one at our track a while back, running low 14s. The only thing was the car was a race car. Big slicks, no exhaust, gutted, all out race car and wasnt even touching 13s (it was a warm day out)!

 

That's good... but choose you're next cam wisely to match.

I'd step up to 3.73's.

I'm not that big a fan of gutting a car out just to run a number (not that you've mentioned this), but in the anemic 305's case... you might have to lighten the load a tad. Every 100-lb reduction in weight usually equates to running a tenth of a second faster in the 1/4 mile.

If you're confident you can get it down to 13.4 or 13.3 with a head/cam/carb swap... then lighten the load as well. Fiberglass hood, notch, doors (while relocating the battery to the rear) should do the trick.

 

My goodness, I didn't even notice that. That is alot of stall!

 

obviously that car had issues with either its setup, or the driver. Dennis91RS proved you obviously dont need a "race car" setup to crack 13s in a 305

 

i was considerin jumpin up to the 3.73s after i got some heads on her

 

Oh Im sure, this is a crappy track, but his car just should have been faster. Im not sure on the mods, but I do know in the NHRA circuit they have some 11 second 305s with strict rules. Its all about the owner and driver and how fast it can go!

 

Thats freakin awesome. Gives me hope for a 12 sec GTA!
