Making 300 hp from a 305
I know there are probably enough threads on this to blow my computer, but I had a few specific questions. I've been hard at work getting the AC and tranny cooler in this week and wanted to make more power while I was at it.
A 350 is in best interest however is not feasible right now. So I'm going to do the usually heads and headers (exhaust already done) and possibly a new cam in there. Stuff that will swap to a 350.
Anyway, my questions are, can I Keep the original 700r4 transmission? As well as driveshaft? Im going to get a new gear ratio in the rear. Also, cant the stock fuel pump handle that power or will I need an upgrade along with injectors?
As a side question, does the transmission mount bushing just come out with the bolt? Had a hell of a time getting it out because of the decay on the bolt.
Thanks! Haven't been on here much, been putting some work into it

Re: Making 300 hp from a 305
Yes same trans will work for both 305 and 350 and will handle 300 HP with no prob. If you want to firm things up alittle you could install a shift kit, .500" boost valve, corvette servo, and a little higher stall torque converter.
With the mild mods you are doing the stock fuel pump and injectors will be fine
The trans mount bolts to the transmission with 2 bolts, then mount has 1 stud that sticks down through crossmember to hold trans to crossmember.
