Dad had a Blazer with a 305 and got 11-13.Best was 14.75 and 11.50
pulling 5500 lbs.I had 1 with a 350 got 13-15. Best was 18.5 and 14.5
pulling 5500 lbs.
P.S. Sorry,but the 305 is a waste of time and money.
Your only losing 45 c.i.
A 350 dosen`t cost any more to rebuild.
You can practically get parts at the grocery store.
Listen to everyone on here. You won`t gain anything changing to a
305.Unless you build it bigger.
