eaglescout526 Posted Saturday at 04:40 AM Author Share Posted Saturday at 04:40 AM Let do some updating. I have yet to do anything. Funds and the Jeeps have been taking my money and time. But wheres the fun if youre not gonna expect that of a pair of 40 year old Jeeps haha. So I did a bit of digging and want to get more power out of this 403. I learned of a popular 350 olds head swap for the 403. I knew where a 350 was in the backyard. So I yanked them and will be doing some cleaning and derusting. I have since learned the heads are 330 heads which makes sense cause the car, or whats left, is a 67 olds. Last year for the 330. But these heads will still bump up my power output like I want, paired with some roller rockers, it should be a real hoot to have and drive.
