right now i'm not sure if want to stick with my 305 and put in the mods i have in my sig, or save up, sell my engine and by a 350 crate engine. i want to run in the low 13's or mid to high 12's, so what should i do? thanks

 

What is it running now and how many miles on it??

 

i haven't taken it to the track yet, but i'd say in the mid 14's cause i raced a 96 auto formula and i was just a tad faster. the motor has less than 20,000 mile on it.

 

Only 20,000 on the 305. How much on the rest of the car, just wanna know??

 

I say keep the 305 for now since it's got low miles. IT's already pretty quick because it's a G92 SD car and well you can squeeze a lot of power out of the 305. Not as much as a 350 though.

 

Dude, I dont want to get yelled at as usual when some one asks this question. I usally say 305's suck. Then some one with a 305 gets mad and goes on how 305's rule. But none of that.
Cruise with your 305 and save money for now. Then when you have enough saved drop in a ram jet 350 with all the goodies.
305 people get off my back.

 

WHAT??? WHAT DO YOU THINK YOU'RE TALKING ABOUT 87irocz350? 305s RULE! I DON'T KNOW WHERE YOU GET YOUR INFORMATION BUT I LOVE 305 IT ROCKS blah, blah blah...

 

umm....if you have a 305 and are lookn for mid to high 13s....stick with that motor...but high 12s? that is 350 territory b/c you can get there MUCH cheaper. .....i am running a 305...not a 350..so you know...unbiased.

 

IROCZTWENTYGR8, my car has 95,000 miles on it

 

For easiness and cost I'd go with the 350 for 12's-low 13's N/A. Anything else a 305 is pretty good.

 

yep the 305 is good down to high 8s....LOL anything else ABOVE low-mid 13s.

 

400 is the only way to go.

oh yeah!

 

You should do this!

 

I've been through that whole deal...deciding whether to keep the 305 or go to 350....i'll tell ya this. You have low miles on the 305, so I'd stick w/ that for now (as a few people have already said) and either save money for a crate motor....zz4 or ramjet...or progressively build a motor. But if you go to a 350, dont do it half *** and get some joe schmo 350...go all out, you'll be happy you did.

 

you have a 305/ 5speed & a G92 package... keep it.

 

ditto ^^^^ i had that......i could beat alot of 350s on the street.... Prob b/c i had a new engine vs their high milage one.

 

Future mods: Holley Stealth Ram, SLP 1 3/4 headers, AFPR, and a 150 shot of NOS


well, you could do what I am doing. Build the 305 using all parts that will transfer onto a 350 block when you are able to do so.
The Stealth Ram, headers AFPR and NOS that you mention as future mods will all bolt onto the 350 later on. Put them on the 305 for now.

Your 10.1 compression is pretty healthy to put a 150 shot into but it looks like you have a pretty tough bottom end to put it into.

Good Luck.

 

From what i have read on the boards here, Sence its a low mile strong running 305 keep it for now and do mods to your car that will transfer over to a 350 later: Intake, Exhaust, Suspension(traction!!), just to name a few. Its all in what YOU want to do with your car. The 305 is a good engine and can make so serious ponies if done right but the more hp you want out of it the more expensive its gonna get. Where as the 350 will be cheaper and easier to get higher Hp's out of, though maybe not right away(gettin the block or what have you). Like i said its really all about what you want to do with your car. Have Fun and good luck

 

305, why not just go with a v tech...
-just joking-

Spend your money on the suspension that way when you have the power later on you'll be able to apply it.
Suspension is alot more reliable than a hopped up motor.

I've seen junk yard 302's put in 3200lb mustangs and run 8.30's on motor.(1/8th) That was on radials. The boy had hell of a susupension though.
He got 21m/g, decently fast car, and a reliable car with cold air and power steering.

Now that's putting your money where it counts.
