Good catch Mike Tkach!

i knew what it was also but you beat me to it lol..your glory,,2 great minds think alike....now the st pete thing..i wounder if someone we know will invite themselves to the same area..

Deal! I should have the Donzi tuned perfectly by then..... I'll shoot you a PM...

who?

just a lucky guess,but thanks

I appreciate you guys chiming in here to help a newb... I have been a Mopar guy for 30 years and know them in and out. Its the little details that always get you and I just don't have
the experience with the marine stuff..... My marine guy just happened to find a brand new, in the box, Thunderbolt IV 24* ignition module with pigtail connector yesterday so I should be able to get this thing running today!

thats good news,keep us posted.

So far so good! Fired it up tonight and it sounds pretty
Beefy! Got a few water leaks to take care of but no oil leaks..... Set the timing at 7* before and primed the carb bowls and it fired off so fast it scared me!! Dogs went running!! Initial fuel pressure was 9 1/2 with the mech pump and I was not happy with that but the Holley 850 HP I was using did not skip a beat....it settled down to 8psi after a few minutes........I have a mighty demon 850 but the damn fuel inlets use a special fitting so I took the carb off a 528 hemi and it worked pretty good! Timing is set at 34* now and has great throttle response..... Motor sounds like it will be a torque monster and should have it in by the weekend....

Just fyi - the v8-24 module does not have all the timing in until 3700 rpm.
If you want the TBIV / TBV manual in pdf - send me your email addy.

Ok thanks for the offer....... my email is my screen name at the yahoo site... Yes, I could see the timing continu to move as I increased rpm..... This engine has a 4-7/2-3 cam lobe swap and it has quite a snarl when revved? Has a different sound for sure......... The Dogs did not like It one bit!
