Looking at picking up a rear locally out of a Monte SS, Posi 3.73, complete hub to hub. How much is a decent price? I can get it for $500, sounds high to me, but maybe not?

Everything hooked up smoothly.. didn't notice any differences. I did not drain the converter... I know I lost a lot of fluid when I pulled everything. I did not take it off the engine I installed. I pulled the TH400 off, then hooked it up to the current transmission. I have added either 5-6 qts. of...

Swapped in the 350 for the 305 in my Grand Prix, used the torque converter from the 350 (that was originally hooked to a TH400), and hooked them to the still working TH250c.. I got the 350 going and it sounds amazing.. use the new ratchet shifter to ratchet it out of park and.... nothing. Show a...

So who knew that a SBC starter from an '84 chevy 305 wouldn't bolt up to a '74 LT-1... buncha poop. Time to head back to Autozone again... I am missing the hole in the block for the power steering pump next to the timing cover too... :puke:

On the 305 I had, timing made all the difference. My 305 liked as much advance as I could give it before it started hard and/or started detonating. I believe I ended up with about 14 degrees initial and 36 total, with 10 vacuum and 12 mechanical advance. None of my friends would believe it was a...

Does anyone know offhand the transmission bolt size/thread for a Pontiac 400, and what length would work best for mounting to an engine stand? Thanks!

Thank you for your help, I will start checking around for a Monte SS rear.

Ok, I looked up symptoms for the master cylinder, and it definitely sounds like that is what it will be. Thanks for your help!

According to the description it has everything needed for a complete conversion. It is brand new as of the newest catalog, so no personal experience, but I have always had a great experience with summits stuff.

I am copping a BOP TH350 from an '81 T/A, and I plan on using it with a 400+ hp '70 Pontiac 400. Should I plan on rebuilding it, and is it something I can do myself using a kit such as this? www.summitracing.com/parts/sum-705020

I just picked up Summit's smallest transmission cooler, rated at 17000 GVW, has some definite bling to it. Hopefully it will still be enough with no internal cooler.

I noticed that my brake pedal started feeling a little different yesterday. Usually it has a really nice positive feel to it, but yesterday I had alot of excess travel before my brakes engaged. And now last night my brake warning light came on. I checked my fluid and it is full, but dark, so it...

Doesn't seem like something I would bother doing when I noticed that this month's Summit catalog has these for the Gbody now.. http://www.summitracing.com/parts/SUM-BK1333/ or cross-drilled rotors... http://www.summitracing.com/parts/SUM-BK1333-99901/

wow... STUPID MUSIC.. I would bet that sounds great. Especially with no enclosures, or even mounted ... :blam: And even to admit that you spent $3k on that..

Just picked up my 400, 9799914 block w/ #16 heads. I think it is my best starting point yet.

I am building a 2nd GP, this one from a v6, using a '68 Poncho 400. I have a '81 T/A that I am using for parts, mostly for the BOP TH350, snowflakes and its posi rear end. My question is what all do I need to convert the rear to use the T/A unit, and is it something someone inexperienced but...

I need some help with what engine and frame mounts I will need to do this swap into a GP that was originally a v6. I have heard on here that to do a 400 swap you need engine mounts from a 301 powered GP, but since this is a '68 block I thought that the mounts were different. I asked Butler...

I was running low on gas today before being able to get to Napa for a couple more bottles of Heet, so I put in a couple of gallons of gas and my car was missing all the way home after that. Added the two bottles of Heet, and filled the tank again.. so, isn't fixed quite yet.

No problems at all with the tank of gas that had the Heet in it. I have already refilled it once, and it had missed a little while cruising on the highway for a second or two, but I have left it idle once I get home to see if it would stall, and no problems. I will add a couple more bottles when...
