Life time waranty for a 3000 dollar motor sounds pretty good. GM offers like 30000 or something on a crate motor dont they? Then again the guy probably knows you arnt going to be using it as daily transport so you wont be racking up miles. Sounds like a nice cruiser

I like the sound of it!

Do you have a slight stall converter in the TH400?

Bet you can't wait to get it in the velle. I think you will be really happy with the median of driveability and power.

BB, Ratlover, Xtreme

Thanx for your messages. They were so meticulous in building it that it bordered on being fanatical! They mainly build high pro Dragster Engines over 100 grand each so they can't afford to cut ANY corners, nor will they.They would check and recheck every part installed. They stand behind any engine they build 100%. Even if this car is sold again and again. I like that way of doing business.Hard to find people like that today.

I am so damn excited! Perfect timing on the weather factor.Will be ready to go in the best time of the year around here!

No slight stall converter as of yet. Guess I want my tranny to last, but might do it at later date. The Cam that was installed is meant to run o.k. without it. I subscribe to the theory that bigger doesn't necess. mean better.

What does a stall converter do? Does every car/truck have one?

Mr. Bum,
"Stall" is the term used to give a guess as to what rpm the converter will allow the engine to rev to before actually applying full power. Here's the theory behind it.
Big cam=not much low end torque, rough Idle.
Smaller cam=more low end power, smooth idle.
The idea of a "loose" converter, rated over 2500 stall, is to allow the engine to rev to that rpm before it hooks up the engine to the trans. It will also allow an engine with a big cam to idle without trying to drive the car. If your cam isn't too big, and the car doesn't want to creep at stoplights, you won't see much benefit from a stall converter.Hope this helps.
Steve

All Converters have a "stall"
Depends on weight of car,rpm, rear used,etc.. A 2300 may stall at 1600 in a lighter car.
Stall" is only a term that relates to the rpm that the converter transfers torque to the trans. The higher the stall speed the higher the rpm before the engine power really gets to the tranny.

Personally, I just used the 180* TStat, and it works fine, I am happy. I didn't drill any holes.
Here is another forum (Suburban) but, a few of the guys have done it. http://forums.vmag.com/suvsuburban0801

Mike,
Some of the older BB are in need of cooling holes drilled in them, not so much that it cools the engine, but helps other parts from getting too hot. On the head gasket are the extra holes to use as a template. Chevrolet notes this since they are in the later 427 and 454 blocks. My engine has '69 heads.

I couldn't get anything out of the truck website. When did they come out with this fix. The only thing I remember is that about 78 the truck 454s changed the water pattern in the block. If you didn't use the correct head gasket no cooling went to the exhaust seats. I saw a set of 820 heads that had the exhaust seats sunk 1/2 in into the head from the heat.
