Re: Crate GoodWrench 350 Questions
I've been doing research, is it true they built it with really low compression so the engine could use low octane gas?

Re: Crate GoodWrench 350 Questions
The goodwrench 350? Yes that is partially true. They wanted a economical engine that could be put in most 1985 and under cars and trucks and pass emission standards everywhere. If the made a 350hp 350, it might not pass some emission requirements.

Re: Crate GoodWrench 350 Questions
Agreed, mostly stock 283 with 225/75/15 tires and 3 on the tree. 3.08 is great

Re: Crate GoodWrench 350 Questions
My 78 big 10 is just like yours, stock 350/TH350 and 3:08, and will hold 70 with the AC on using the cruise going uphill with out any trouble.

Re: Crate GoodWrench 350 Questions
I agree. I was referring to it loaded AND going uphill. Like with a 1500 slide in camper and another 700lbs worth of stuff inside.

That totally makes sense. I just couldn't figure why they would deliberately build it to be a dog - It needs to pass emissions in every State in every car. Here in Oregon anything around 1974 and older doesn't have to do an emissions test.

Re: Crate GoodWrench 350 Questions
Is a stock gm Goodwrench 350 good 'as is' for a truck application where you are mainly concerned about fuel economy and low end torque?

Re: Crate GoodWrench 350 Questions
Mediocre. I had to swap to vortec heads, cam and headers so it could get out of it's own way.

Re: Crate GoodWrench 350 Questions
I think its fine however, these days a roller cam seems to be the hot ticket because of the new oil. I do fine with a 283 for just driving around so that 350 should be great for driving around. Especially if you have dual exhaust and a nice aluminium dual plane intake. I dunno I've seen many a smokey burnout from a stock Goodwrech 350 in a classic truck.

Re: Crate GoodWrench 350 Questions
ZZ shortblock, summit vortec heads and a dual plane intake is the ticket right now
