Don't expect it to be a screamer, but it should get out of it's own way nicely....

Bull **** it wont run 12's. I had a 305 in my car just like what he is going to install with a smaller cam (210/215 @.050 / .452.470 lift) that ran a best of 12.56 @109 on a 100 shot. Look just set the car up with 15 initial timing, and run a ratio of about 3 or 4 gallons of 93 and 1 gallon of unleded racing fuel on the spray. You will probably run at least a low 13 high 12 when you get it tuned out.

That's true. I worked at making my 305 fast but never could quite get it. My old friend got an '89 305 Bird too and put a few stickers on it. Blew me off the road!!!

Re: 305 build up.

Don't dare come around here saying you are building up a 305. You just dont do it man.



Seriously, stop bashing the people with 305's already. Just because you have a nice built up 350 or bigger doesn't make you God. Yes, I have a 305, and yes, I will be building it up to achieve a 13 second car, but that's all the more I need, and probably all this guy needs. Not everone wants to make a wannabe NHRA car outta their Camaro. Better yet, I'll get a 454 and tell all you 305 bashers to "stop wasting" your money on such a wussy engine. After all, the more cubic inches you have, the better, right?

Re: 305 build up.

Hey Rice Killer, I dont know how well you pay attention yourself around here, but bashing goes on all the time with people who want to build up 305's. Look around for some of these threads and you will see what I mean. It's obvious some people in this thread are already indirectly bashing the 305.
