Here is the old 305 ready to come out. Nothing wrong with it besides the usual oil leaks. I just wanted more horses to pull my boat with.(And for a bit more... Show more street fun!)
This is the 350 I traded for a wrecked Chevy Blazer. It's a Goodwrench motor with 60K on it and it ran on propane so it was nice and clean inside.
Dirty outside, but I fixed that.
This is the last time it breathed 305 cubic inches.
And Stay Out! I never was very happy with the gold colour scheme I chose for the old block, although it did spark a lot of questions. The new chevy orange really sticks out now.
A hungry void.
The freshened up 350. I was told the car originally came with a 265 or 267 and a TH250c or TH200c tranny. The vin number always confused me because the engine code is "J"(i.e. 4.4L-267 cid) which isn't even shown in the original service manual as an option. Regardless, the car already had a Chevy 305 and a TH350 when I bought it but neither lasted to long.
A used 305 replaced the oil starved unit before it. And a new TH350 found it's way in after an unfortunate "stuck in the snow" event. The used 305 was later rebuilt when the car was completely torn down and rebuilt.
5.7L of (How much per Liter?) gas guzzling fun. Oh well, the price at the pumps is really not the point now is it?
The old TH350 started slipping shortly after the 350 was put in so I installed a TH200-4R. Just for clarification, in a TH350 to TH200-4R swap, the TH350 crossmember will not work without modifications but a later model g-body with a TH200-4R crossmember will. If your car is 81-83 you will need to extend the crossmember support frame on the drivers side to get the newer crossmember to work, but 84 and up already has the extension from factory. The driveshaft works fine and the length is good. There should also already be wiring for the lockup converter already in the car like mine had but you would have to see how many wires are required on the new tranny.
The Goodwrench 350 in it's new home.
It's amazing what a difference an extra 45 cubic inches can do.
I recently picked up a new set of Richmond 3.73 gears and will try to install them in the next couple of months. I will try to post some pics of the process. They should make quite a difference compared to the stock 2.20 gears that are in there now! Show Less
