I don’t have the PN with me but on my old 1990 330hp 454 with the Thunderbolt ignition ( I am pretty sure is a V8-24) system what was the rev limiter set at?

Tbolt IV modules do not have a rev limit function.

No rev limiters on TB IV's. On Blue engines with TB IV's they use a separate rev limiter.

and i wouldnt buz it over 5000rpm.I think its rated at 4800????

My '89 330 was good to 5500 extended runs and up to 6000 bursts for six years then it stuck a valve from bad riser gaskets. It's a really good stock motor!

You must of did some work to it?

My 365 mag with headers,1.8 rockers,and holley 830 carb was flat about 5400

I have the same ignition system from my 330 hp 454 on my 500hp 502. I cant seem to get over 5100 rpms out of it. So are you saying there is no rev limiter on this motors system?

THAT IS CORRECT NO REV LIMITER. 5100 IS WERE YOU WHANT TO BE

[QUOTE=Strip Poker 388]Just prop size and timing on that motor

Yep, NO rev limiter.
