Hey all, I havent been on for a while and just wanted to say I picked up a 427 tall deck with 4 bolt mains 1 piece rear main seal for 400 bucks. I cant wait to build a torque monster 496 out of it. By the way my 0 mile 400 hp 350 is for sale. email me @ dmhrehir@telusplanet.net for info.

what did that come out of? a medium duty truck? i was curious about this engine too, but no one on the board really had anything good to say about them. i have seen at least 2 board members now running them. i forget names, but one is a 4x4 blazer with 44's. seems you can score the engines cheap, and they are almost always low-mile units. keep us updated on the progress.

A 427 tall deck is what my boss runs in his truck. Also pulled sleds in competitions .To this day no problems..
here is the thread.

I am going to try and get a good picture of it this week..http://67-72chevytrucks.com/vboard/s...threadid=74332

Dean23 · 10-27-2003, 04:29 PM

the engine is out of a medium duty truck. they r a good engine with the tall deck height all u need to do is put a spacer in to run any aftermarket intake. Plus u can build huge cubic inches out of these engines. the only other difference is that u need to use a longer distributor and fuel pump pushrod if u r going to use a mechanical pump.

Dean23 · 10-27-2003, 07:16 PM

So people lets get all your opinions on the tall deck engines

blue_69 · 10-27-2003, 07:24 PM

i have a 366 tall deck. It was in my truck but the truck is in a million peices right now but the engine has always run strong. If you dont want to spend big bucks for an aftermarket distributer do what i did have the ridge taken off a stock gm one at a machine shop then go to you local industrial supply store and buy a lock collar that fits the distributer. Then you can adjust it to the height you need.

Dean23 · 10-27-2003, 10:51 PM

Dean23 · 10-28-2003, 01:34 PM

Dean23 · 10-29-2003, 09:30 PM
