Delta Cam Scotty J spec'd 276/286 @ .050 .752"/.771" on a 113 Lb sep

New TFS Intake 4500
1250 Qfuel carb

On the third pull we hit my goal for above 800 horsepower !
Ran 11 more pulls to fine tune jets, carb spacers, timing, headers, and fuels.

Ended making 845hp & 712tq

Dyno sheets attached.

All runs were with Hedman Hustlers fenderwell exit truck headers with 2" x 3.5"(EGT Bungs) On the 836hp pull the oil temp got high at the end and engine was shut down and recorded the low oil psi on the graph, Next pull it was right back.

On the 845hp run there no EGTs as those were my 2 1/4" x 4" Uprights ceramic coated.

I am very pleased with the results to say the least. All info and parts from members and venders on this site. Dyno sheets below.

Thanks, not in any particular order for either parts or advice from a-z

Nice numbers there Mark. Too bad you couldn't have had a comparison between the TFS and the Victor intakes. That thing is going to boogie in the mud pits.

Wow... with iron heads!? awesome!

Nice build for a sweet truck.

Nicely done Mark.

Just shows that it takes a village to raise a hell raising stroker...

very nice numbers ...props to all involved !!!! .....

yep!! them old dooe-r's can rock the chevy world i personally know my self

Very impressive numbers for some ole FOMOCO iron. Congrats. Billy

When I swapped my TFS Street's off and put my ported Cast SCJ's on nothing changed on the combo no tuning or anything , it ran with in a tenth of the aluminum ported heads. That was with one point less compression and 100 more pounds.

Another point to make here is the exhaust only flowed 50% of the intake and still made power. I guess that kind of blows the Chevy guys therory of you cant make power unless your exhaust flows atleast 70 % of your intake.

The old Ford iron are bad mamajamma's. I always wanted to put the right cam in mine and tune it on the dyno to see what it would make. The TFS's made 860 hp.

You have a nice power plant............... Congrats to you.

Very nice build.

What an awesome powerplant you have!!! Great job guys

Dang I need that in my tube chassis mustang to see what it would run! I have ported D0Ve's on my 514 and the must not be flowing enough, lol

That is sweet. I have a set of the DO0E heads and a set of pi's. I have been considering selling the pi's jut to get alum for weight. I might just hang on to them.

Holy Shit I Just saw this thread. Awsome piece. Try that with a IRON PRODUCTION head BBC. You will need a big blower or large shot of juice to even come CLOSE.
