ok i`m shootin for 13`s on my original lo3, so far i got a box stock tpi, a skip shift eliminater for the th700, jet 3 piece pulleys, i may get slp runners, hedman full lengths, qtech cut outs. dont know what it runs but i hear alotta guys have probs around 14 flat i may just camm it i got stock head with 1.6 rollers coming, what kinda cam would u guys suggest?
i have plans for next winter to put a mas performance 350 with 383 hp 408 ftlbs with a carb i`m gonna stick a steath ram on it.

 

You won't hit 13's with that setup

 

if your using a tpi

s/r tourquers heads
comp extreme energy cam
headers with 3 inch cat back
3.42 posi gears
stall converter
tuning the prom
suspension mods

say hello to high 13's


i hope

 

I agree with Mikobu3 but another idea i would perfer is to use the stock heads and port them(not extreme though, it is a 305), port and siamese the base, SLP siamese runners, port-siamese and radius the plenum, use your Hedmans, qtech's, pulleys, and 1.6 rockers. All that gasket matched and used with a Comp Cams Xtreme Energy cam XE250h 206/212 Lift .432/.444 LSA 110 would work good without ECM work. Although a good burned prom be be great. Dont forget to add in all the free mods that will help. But everyone has their own suggestions and im curious to see theirs.

 

I would recommend a better cam. That one isn't much of an upgrade unless you have the peanut cam. I would recommend the XE252 or XE262. 110 LSA is too low for 305's with automatics.

 

the cam i was talking about is extreme energy 212 -218 449 -456 112 lsa , this will run good with stock chip also good for about 40 hp over peanut cam , the cam works from 1200 rpm to 5200 rpm

 

I was lookin at the xtreme energy cams. i got 3.23 gears with this setup i`m camming it to make sure i can hit 13`s, i got a design for an almost free cold air intake off f-bodyhideout.com. i almost wasnt gonna mess with the 305 and was about to get that mas 350, but a 13 second 305 is a sleeper in my book hehe.

 

Some guy on here tells people his 383 is a 305. I like that one even better.

 

lol. when i get my tpi on mine i`ll tell ppl its a l69 with just exhuast mods ppl wont hesitate to race me for green.

 

whats all this crazy talk of 13 second 305s hahaha

 

Consider this Cam: Crane Powermax 2032 452/465 214/220 112 deg. P/N 104224 $328.00 or $269.99 or $259.95 @ summit!

 

Whats your mods SLP IROC?

Blah he's got 187 castings. Porting them is a waste of time.

Heads and cam are going to be the biggest restrictions.

 

 

i competely agree with mikobu3,
thats pretty much my setup so far--
well not aof it but some of it and others sitting in boxs in my room.
but i am waiting till my motor blows. so i can just rebuil that 305 and have my LB9 heads ported and new 1.94" intakes valves installed. a new cam along with a set of SLP runners and a ported base-

 

well i`m tryin to hit 13`s on the original motor since day1, all my setup needs probably now is a fast ecm, cam 3.73`s and an aluminum drive shaft. as far as my head casting go i can only find out what they are by gettin the number under the valve covers. gm made a ton of 305 head casting most cannot be listed in one place. i may just get some heads that can be switched with a 350 so i dont waste ne money on it.

 

I also see a huge advantage over ford`s 5.0 in the 305 considering its a deep breathing motor ford`s 5.0 is a squeeze motor best setup for road racing.
