I think you are doing the right thing vs swapping in a 9 inch. I watched your other video and it's a N/A small block, I'm not trying to talk down on the engine but it can't possibly be making a huge amount of HP, and the car is a light car. So, I think a 9" swap is overrated on certain cars. I've been saying for years why not just put some chromoly axles and an aftermarket posi in the stock axle. Obviously a th400 and a ford 9 inch is the ultimate, but supposedly they have more parasitic loss than let's say a th350 and a 10 bolt. because they are literally bigger and heavier stuff. The only problem is that you might outgrow that 10 bolt once you start adding turbos and stuff like that. but all that doesn't matter build it, show people what it did and thats all there is to it. Thanks for sharing what you are doing.

What's a "huge" amount of horsepower to you? Small block Chevys (or BOP) have been built to at a very wide range of horsepower and torque levels.

@@focused313 Well it's a N/A small block chevy. I think it's a 383 I looked at his other videos, but I forgot. I think a huge amount of power is like over 500 hp over 500 ft lbs. Something that you won't hardly achieve with any small block unless its boosted. Or if its running on alcohol. I'm pretty sure if you have a set up like his it can handle probably any NA small block, but that's just my opinion.

I hope your still monitoring your chats. I'm currently Replacing my 1969 Pontiac Grand Prix Model J. Entire Rear end. I'm asking should I just Go with a complete swap with a Ford 9" or a GM 8.5". Your thoughts please is much needed. I'm still at the disassemble phase, due to the right wheel came completely out while driving. OH, and all Original Parts I had heavier Crome wheels on it and was rolling Hard. Hell to hard.

Get the best you can afford. If a 9" is in your price range, get that. I just upgraded my gm 7.5 because i see others run some good times, and my car has been gutted, so you can get away with a little more without a full weight car. But it depends on how you use your car.

When I added the cost of the parts you listed, it was nearly $1500 (summitracing pricing). At what point do you opt for a crate rear end from a company like Quick Performance, Strange, etc... for roughly $1k more (I realize every dollar could be spent elsewhere). No criticism, just trying to learn.

I looked at quick performance g body 9" rears, and they start at $2,215, but the price goes up when you go through and select the stuff you have to have to go with it. But I get what you saying this just for the people that don't need a 9" or can't afford it. Or just want to keep their gm car all gm for cheap.
