hmmm smallblock... a 400 bore and 350 stroke 374 bowtie block !
Thinkin of a pair of 383īs and Darts plus some work plus good drives and off to a good start...
How high did you spin them engines in it?

24degrees

No problem.....you and I probably think alike.....

AppSysCons

4.125 bore x 3.50 stroke = 374cid
7700rpm, 1.50 drive ratio, 24 4-blade = 102mph

MikeyFIN

Whoa..7700 constant...That has been a Screamer!
How much hp ? 500-550 per engine?
Iīd have a spare Kinsler Stack f.i unit and a Donovan 400 Al-block for spares...
But instead was thinking on the lines of a pair of 383īs and Kinslers...hmmm I might have to go and take at look at that hull....

AppSysCons

650hp or so in 1998
670hp or so in 1999

did you guys do your own motors ?
sounds like a great combo.. the video is great!
what type of deck was on it? who did the bolsters?

all the best

Hmmm Dart II Sportsmans and almost 700....Prolly done a tad more than pocketportin...
Iīd love to test those heads on my flowbench... 6 inch rods or 5.7 and lightweight crank ?
Donīt have to tell me If you donīt want to but also how high a compression in static and how high cranking pressure (@220) ?
And a "quite" stout roller too in the neighbourhood of 250degr at 050 with a 0.600 lift?

The race boat started as a 1971 Magnum sport cruiser. It had T/Volvos, cabin, head, and
kitchen. The deck was cut off and throw away. The hull was ground down to a few stringers and totally re-build using dupont kevlar, new stringers, new bulk
heads and new herring bone(cross bracing) was added. All of the hull, deck and dash work was done by Dave Fox of Fiberglass Services, in Banregat LIght, NJ. An Activator deck was taken ,cut
down the middle from bow to stern using a radial saw. Then extra material was added to
widen the deck and this was used to fabricate a new deck. The dash was patterned of an
Apache. We went to PA and used the race boat Predator as a pattern for the dash.

The bolster was done by a friend in the upholstery business, he ran the boat Indigo, a 30 scarab, also build by Dave Fox.

We did the motors mostly ourselves. We did have some help from time to time from two
freinds, Dale from Predator Carbs and George from Auto Enterprises. We also had some
help from Doug and Tommy at Professional Marine Racing , when we first built the high
compression motors.

So when did the Runaways race history start?
Hmmm Dale From Predator was involved...figures
Remember when Predator Carbs hit the Street Racing Scene in Scandinavia in the mid 80īs...

I have the flow bench data, the compression, cranking pressure tests, and cam cards somewhere, I will have to dig them out. We used 6 inch rods and a 4340 Lunati crank
