Matt Shaff's Engine Shop / Piston questions
« on: May 07, 2020, 06:39:44 PM »
I need to order pistons soon for my next engine.
The specs  solid cast aluminum Buick block no water jackets.
Heads flow 490 cfm. at our cam specs and rocker ratio.
Crank is a 3.750 stroke 7.0" rods
Bore is 4.500
Gasket range .040 to .100
6:71 to start and may move up to an 8:71 later.
Enderle injector and port nozzles on alky.
We are shooting for about 11.5 to 1 compression with the .040 gasket.
This is going in our Supercat FED.
Questions are;
1 how far down for the piston?
2 how far down should the top ring be?
3 what style top dished,  flat, ?
4 should the pistons be coated?

Let me know your thoughts folks.
Thanks
John

Could anyone running a gilmer style oil pump drive and supercharger please show me a few shots of your setups?
We will be running our new Dailey engineering Oil pump/ fuel pump drive on the new supercharged engine and I'm curious. Do people like sandwiching the gilmer pulley between the hub and blower pulley or off of a drive extension in front of the blower pulley?

462" iron Buick , 4 port Hilborn  1/2 pump, pg 1.82 , 3.89 rear , 12x33 Hoiser C09. Car is about 1650 race weight.

Thanks for any guidance

Has anyone run their car at the 1/8th mile track at Winterport Maine?
I had run our Wildcat there years ago . I'm running the Supercat FED 9/10 at the Gassah Guys event that they run monthly. I'm really looking forward to it. It's about 20 miles from the new house in Maine.

Let me know if you plan on running or have ever been.

Events / Bowling Green 2015 who's going
« on: April 22, 2015, 06:59:45 PM »
Just wondering who is going and what are you bringing to the event.
We are bringing the 200"Supercat FED. We are running well and have made many changes over the winter. With a few more changes to go before BG. What classes can we enter if we are well into the 7's . Do they run the Heritage rules or are there other options?

So what are you bringing and what class will you run?

Thanks
John

Front Engine Dragsters / Pro charger question on a Fed
« on: November 12, 2014, 07:00:38 PM »
We are trying out a VERY Large Pro charger F3R-139(gear driven) on our 445" engine in our Fed this winter.
What NHRA/IHRA classes can we run in with the procharged engine in the FED?
We were thinking Top Dragster or A fuel any other classes/thoughts ;D.
We do have the intake parts to make the 671 intake in the future but for now we are looking at the possible options for this combo.
Thanks in advance for any input.

An earlier picture of the mock-up to make sure it fits inside the body....... Only parts to be seen is the throttle body and the pressure pipe.
