305 engine builds

[FKRACING]

SO, How many people have built there stock 305's up? What's the best things you have come up with to make it perform well and or great? I personaly have built a LOT of them and alway like to hear about others who have done so as well.

I am anxious to hear as well. I plan to rebuild my 305 and want to keep the car looking all original under the hood. I would like to hear what cam is good and if porting and polishing along with the cam and a little compression bump would do for the engine. I don't need gobs of power, but just enough to get the stock car out of the complete dog mode it is in.

When everyone gets over their New Year hangover I will be intrested in hearing your replys to the op's question.

My car looks original, and runs a 350. Unless you read casting numbers, 99% of the world will never know if you have a 262 or a 400 as long as you paint it black, use stock valve covers, and run a Quadrajet. Bigger engines are so cheap as cores that it just doesn't pay to run a 305 when you are rebuilding from scratch.

If you have a good running 305 in your car, and you are not looking for a street screamer, there are plenty of things you can do to get it up in the 275-300 horse range without sacrificing reliability. Vortec heads are a great upgrade. If you want the bone stock look, World makes an S/R Torquer 305 head that is worth about 30 horse over stock heads. The stock aluminum intake is a pretty decent piece for a factory intake. An Edelbrock Performer or equivalent is a good upgrade though. A performer RPM is too big . Cam selection for a 305 is tricky, due to the bore and head port size. I called Comp Cams years ago and had help with my selection, but the specs have slipped my mind and I can't find the card. I had a 305 HO with the cam, intake, and slight port and valve work on the stock heads. Also had headers and full dual exhaust. it was fun, and quite a lot better than my stock LG4 305. Even got around 20-22 mpg! But it was no 383, so it now sits in the corner of the shop until i find another gbody to throw it in.
