Q:

bought this Flexplate to use on my BluePrint 383 crate motor.I need a torque converter between 2000 and 2400. Can you recommend one?

Asked by BRUCE on February 06, 2018

A:

Thank you for your question. You didn't mention the transmission you're using so we'll assume a GM TH-350. If that's the case, Hughes makes a great converter in a 2,000 RPM stall as part number HUP-GM20. If you're using something other than a TH-350, please copy and paste this link then select your transmission from the left-hand web filter:

What is the bolt circle pattern on this flex plate?

The bolt pattern is erratic (can only be put on one way) the bolt pattern diameter is approximately 2.990. I hope that answers your question.

Q:

Will this work with a b&m 10” 2000-2400 converter. It says you need a small bolt pattern?

Asked by ERIC on December 18, 2018

A:

Thank you for your question. The Summit G104SFI flexplate is drilled for both the small 10 3/4 in. and the large 11 1/2 in. bolt pattern.

I installed this flexplate on my 1971 Nova's 383 Stroker engine with a 700 R4 tranny. Ease of installation and performance has been excellent.

Pioneer flex plate for SBC

SUM-G104SFI
This plate was terrible quality . The flange was not on the same plane as the ring gear which is why I was buying a new one to replace the one with the exact same problem . In addition it was stamped made in the USA when actually it was made in Mexico !!

Performs just as it should with no problems. Bolted right up with an excellent fit. Dual converter bolt pattern is a bonus.
