Could you PM me or give a list of your previous mods. I mean how the bottom end of your block was done. Also, with you little m block, did you have any clearance problems with the 6" h-beam rods?

What size are your pistons?

Hope I didn't ask any repeative questions, I used the search, but when you search for Guidos setup, it's usually pretty basic.

Just trying to get some ideas.

 

Try looking at my webpage first. If you dont find what you want to know there, then ask again.

I had hte little M clearnaced for my 6" rods.

 

I went to your page, clicked on Mods. But the majority of it is based on your turbo setup. I'm curious more about your old setup.

I saw that it showed the time and 400 vortec, but nothing more.

On your little M, you had a machine shop build it or just clearance it?

 

Internals then are the same as they are now. I just went from a factory 400 block to this new one.

.030 over 400
JE pistons lowered ringlands
6" Eagle h-beam rods
eagle 4340 crank
9.2:1 compression

had to clearance both blocks for rod clearance. I have never let a shopa ssemble my motors. Dont trust them to do as good a job as we would.

 

Alright, thanks for the quick response.

 

Guido, did the 400 block give you problems or did you do this is a preventative measure? I'm starting a TT 85 TA project, and I don't want to have to do this twice. What do you believe the limits of the stock 400 block to be in a turbo application? I have made near 600hp with one in an NA application with no problems, but I want a lot more than that out of this car. I'm thinking I'll probably need a Little M, or maybe a Bowtie (can probably get a good deal on a used one).

 

Preventative maint. Tory Hess on this board broke a 400 block a while back making less power than I plan to with this motor.

Seemed like a good idea.

 

Thanks, thats what I figured. Anyone know of a good source for a little M, new or used?
