What are the best small block to big block conversion mounts?

[Jeremiah]

Howdy,

I am considering switching over to a QA1 k member which will require LA to B motor conversion mounts. Any thoughts on which set to use? 440 Source, Mancini and others offer kits.

Thank you for any insight!

I have had good luck with the TransDapt units.

(Assuming you need the biscuit type mounts, and not spool type.)

This is a streeter so I am trying to stop short of the motor plate and other associated modifications. I have two cars with AR Engineering plates. The motor plate is much easier to deal with IMO.

I love B1 Heads, Just sold a set of B1 PSO! Wish Id kept them!!

Some guys have recommended to me that even on a street swap I use a motor plate. On a B/RB this is relatively simple because you can just shave off the rear of the pump housing by the thickness of the plate, and still use the existing pulley setup. This frees up a fair amount of area for exhaust, etc

schumacher are the nicest in my opinion. have the transdapt ones in our dart now and don't like them. cheap imitation of Schumacher in my opinion.

I like the headers also due to multi purpose. If you bust a knuckle you can carderize it no bandaid needed. . Also hotdogs , Hamburgers and steaks wrapped in tinfoil can be warmed up in your pit area for a quick meal. Not to mention hand warmers on those cold mornings after maintenance.

Schumachers are now built and sold at Motech
Perf. in Murrieta, California.
They are a nice product and the owner Chris will go
out of his way to help you.
He did that for me consistently!!

I agree 100%. This is an original 383 4-speed GTS so no welding or cutting. Streeeeeeeet car lol.

I have a car with an tunnel ram/ Indy -13 w/ Ti valves and a Lenco...and a motor plate. It has glass doors and lexan.

My other motor plate app is a 511" (1000+ on n20) with a G-Force GF5r 5 speed, 2x beadlocks etc. More of a strip-street car.

The GTS is more of a run to the hardware store and stop at the local track for grudge night on the way home kind of machine. Motor plates are shiny...and for race cars lol.

I used Schumacher mounts to locate a mid plate and front plate with my mock up 400 block and gutted 727. It did take some wiggling around even with the Schumacher mounts but it worked well.
Oh I just read your gts is a high dollar car, disregard the mid plate and front plate, however it's easy to remove brackets and welds if you plan to bodywork and restore the car

16.25 is the measurement from the driver side frame rail ? I have to check mine again, I did get 2.5 inch difference but I think mine is a different number off by an 8th of an inch.

I agree with John. The diagram on the instructions was a little off in my application, but with loose factory tolerances and years of fatigue, that should be expected.

you can do the same with small blocks. i had 1/4" machined off the water pump mounting face of the timing cover for a small block so the pump still sits correctly spaced and the pulleys all line up right with the motor plate sandwiched in there.
neil.

 

[Oldmanmopar]

Or you can buy this timing cover.

my, that looks expensive. also my way eliminates the corrosion around the water ports where the pump attaches, bringing you back to good material.
neil.

As soon as my Steve gets into the other shop he wants to copy it. The material is getting expensive.

 

[Jeremiah]

Lol not that any of that has to do with a big block, motor mounts or swapping from la to b motor...

Carry on : D

 

[Jim Lusk]

First I would question the switch in k-members.

 

[Jeremiah]

You do not like the QA1?

I don't see a need. You aren't saving any weight (factory k-member is under 35 lbs) and not solving any problem.

I am mainly looking for clearance to make maintenance less frusterating. I agree on your other points.

 

[Bakerlite]

Schumacher? Yeah, I have some here. They suck.

Specifically what sucks about them? If they suck that bad will you be selling them?
