Has anyone switched their 305 TBI to a bigger motor?
I Have a 91 RS with a 305..But I'm lookin to drop somethin bigger in there and want to put out at least 300-350 hp out of the motor itself..Or can I just beef mine up some how...So if anyone has beefed up their motor or did a swap could you let me know what was done and around what price it was for the acc. or the motor and to have it put in and stuff...And where you got the motor from....I have about 2G's to spend so anything would be a help

My website has a complete price breakdown sheet and even steps to take when installing the 330ho crate motor.
Cost me around 3G's but that's for all new stuff. I could have done it for way less.
