Just looking for advise. I have a 1996 Scarab 22 with same 454HO roller Gen 6 engine. I upgraded the cam to a GM marine 622 (483) lift, marine Edelbrock intake and now I want a little better distributor than stock. Any suggestions as I won't be turning over 5000 rpm's. I see several manufacturers out there and I'm leaning toward the D.U.I marine for 319.00. Thank you!!

I had the same boat and motor combo. I ended up going with an MSD pro billet distributor and 6L 2M ignition. I believe they sell it as a package deal.....

OK, thank you. I'll check into that.

What's wrong with your Thunder Bolt? You are not going to gain anything changing it. The TB is very reliable.

No gains changing and first thing you will lose is reliability

. And Money😎
