Tag in a GT 21?

[BUIZILLA]

what year was the first 360 Mopar marine produced...

[Conquistador_del_mar]

That is the Hull Identification Number 21-56 the reason it is not on the transom is the boat was started in sept 1971 and invoiced in aug of 1972 right before the HIN became mandatory so it is NOT a 73 .

the records indicate the engine serial number was a late scratch the 320 CC was scratched in favor of a 375 chrysler, it was sold to south river. I guess they never printed a new tag

the drive serial number is for a volvo 270 not a trs so judging by that and the condition of the tag some work has been done to the boat.

can you tell what the original colors were?

Matty,
I knew the engine serial number sounded familiar on the GT 21 tag so I found a picture of my 1971 18' tag. Mine was originally equipped with an LT-1 Chevy - 350CID/350HP mechanical lifter motor and the serial numbers are 611131 on mine and 611133 on the GT 21 (only 2 apart). Interesting I thought.

yes pretty interesting they probably were shipped to Donzi in a stock order. The 1971 sbc LT1 was a beast the cig 19 had one in it and it was a screamer for a long time.
I guess 1971 was the golden days of the muscle car by 1973 most motors were detuned and deballed

I was good back then what was available in the car world was made available in the marine world

[mattyboy]

the records show the chrysler motor has a serial number that would put it into a 1972 production date the 375hp model was a 440 the 360 was produced from 1971-2002 was 255 hp in 1971 , the 340 was rated at 275hp not sure they could mate a 440 to a volvo in 72 wonder if it is a typo and should read 275hp that would be within the engineered range of the 270 outdrive.

still digging

[mattyboy]

What are the possibilites? Don was having this boat modified w/ lighter, state of the art materials and it's a one of a kind 'diamond in the rough'? Can I retire early???

don't think so Don had nothing to do with Donzi at the time your boat was built He was putting Cigarette Racing Team on the map. Unless this is a 21 cigarette??


may have been of some value if the original power plant and drive were still around, But that doesn't make it an unworthy project Boat it is just not an ultra rare ultra sort after Donzi.


as far as the tag being wrong i am sure that is not the only one , putting 30 or so boats out the door in a month that means there are 30 or so drives and motors around.......... they were still built by humans.



Bill

they must have had a stocking order on the LT1 motors around that time there are serial numbers from like 611124 to 611135

How did the 21 Cigarette compare performance wise to the GT21?

If an LT1 went into an 18' with the VP 270 drive, there should be a cutout in the engine hatch since the high rise intake was too high for the hatch. Thus mine has the scoop that I found out on this site was originally from the Cigarette plant. I wonder if all 12 of those engine serial numbers were LT1s?

[yeller]

I just bit confused....which isn't out of the ordinary.

Who owns this boat? Xmetal, did you buy it off 73donzibob or does he still own it?

[73donzibob]

We're in the process of working out a deal. Although I still own it/have it, I suppose you could say it's XMETAL's boat.

Most were labeled as a 320 hp Chris craft motors they had the high rise intake with the snowflake stamp and the corvette valve covers I think CC called them an flv350

Yep, the original LT1 was a CC marinized FLV350.
