Re: 67 GMC 305 V6 swap to a SBC 305
Wow, 375hp from a 305 might be a little high estimate. Ditto for 22mpg. The problem with the 305 is the small bore that restricts you to small valve heads and therefore less flow, not to mention valve shrouding...... now a big cam is completey out of the equation.
About the only decent head for a 305 (without breaking the bank) is the l98 aluminum head. It still retains the 58cc chamber. Just speaking from experience: I built a mild 305 with 4 barrel FI and Megasquirt and when I was done I was happy. Then it wore off 2 days later and I said to myself, what the hell did i do that for? I could have spent less money and had 50 more hp with a 350!!! Its fun to be different, but if thats the case, keep the 305 v6. Think of it as half of a GMC v12! (which it kinda is......) Good luck and have fun! And welcome! You will learn much here! Last edited by 5150.4.67; 04-14-2011 at 12:17 AM. |

Just for comparison, I built a 350 and put it in an 83 Chevy Caprice Wagon. My next-door neighbor had the same car, except his was an 84 and had the 305. Mine had more power and better mileage.

Re: 67 GMC 305 V6 swap to a SBC 305
I dropped a 305 in my 68 I took out of a 91 camaro. it was almost free as I traded some very easy fab work for, and I'm not gonna be done with my 502 for quite some time so I figured why not. plus i was tired of pushing the truck around the driveway. it Was a pretty routine motor swap. Easy enough for a beginner. 375hp is a long shot though. thats all i can help you with in terms of power since she has yet to leave the driveway. I had a PO installed 305 in my old 71 c30 dumpbody and that thing couldnt get out of its own way, but then again it was a one ton with a ton of weight in the bed
