I have a tsp 408 with Callie's compstar crank and a 4l60e, will the 399754 work or will I need the 399753?

Thanks guys

You will need the the latter, guaranteed.

Correct, 399753 has the 4L60 LS bolt pattern. Just make sure the converter is built for an LS engine.

Will I have to use the spacer on that flexplate ? If so on the engine side or trans side?

Thanks

The 54 was for a 4L80E style or 350/400 style snout-the FW went on the crank, then the round spacer made up the .400 diff
The 54 FW had a small spacer attached so the FW aligned with the starter
It came with longer metric bolts, but some stroker cranks had American threads-I had to hunt down correct bolts for mine
Cant remember if the 53 is the same FW w/o the snout spacer and bolts, but as said I think its a dual pattern for smaller converters
You need to meas the snout height on your converter in relation to the pads

I'm selling a 399753 flexplate if you decide to go with that: https://ls1tech.com/forums/parts-cla...-399753-a.html
