Re: 86 High Sierra

the engine is in need of some serious help. It hardly runs doesn't downshift properly has no response. so time to freshen the 305 up. I know the 305 the world best boat anchor I've heard them all. but whatever i use will bolt on to a 350 when the time comes. trans fluid has some miles on it but not burnt and the transfer case works fine.

Re: 86 High Sierra

Couldn't reuse the valve covers so decided on some cheap chrome ones. It's amazing what sitting will do

Re: 86 High Sierra

Figured out the coolant leak. I didn't lube the o ring under the water neck. And upon closer inspection I put the fuel filter on backwards.
