BuzzLOL . What ever happened to bygddy and this dual quad 383" engine w/ 244/244 cam? Still waiting on the video...

BuzzLOL . Seems like only yesterday that '41 Willy's was leaving the factory here... LOL!

Fang16 Slicks!? lol No room to carry them, even in my little trailer I pull behind my Willys. Old guy at the track told me one day, seen a lot of Willys on a trailer, never saw one pulling one! lol Running M/T street radials now. Maybe I'll get a car trailer and put some miles on my pick-up. lol Will take the fun outta drivin' to the track tho.

F-BIRD'88 All my stuff is street driven and track raced. My tuneup is exactly the same.
I never even lift the hood at the track other than to allow the engine to cool between rounds.

When it is right it is right. That is a beauti car for sure...Fang16

Everything I recomend is for a street driven car. Then take it to the track, bolt on your slicks, set the tire presure and hang on.
The tuneup is exactly the same.

80% Street/ 20% strip car
16 MPG at 75-80.
11.97 1/4 ET best to date. Just getting back into it at 63. Forgot a lot and have a lot to learn but having a ball doing it. I drive my cars. Vette, blown 350 29 Ford coupe and the Willys. Building a blown 350 for the Willys now. Poor old 98 Ford pick-up just sets there. lol Even drive to the track, 85 miles (Mokan) or 130 (Tusla). Thing is, have fun with what ya got. Some of the guys on here are very competitive and only do track time so their advise does not take the street into consideration.

1971BB427 Hope you'll do a video when you fire the engine up and post it here! I'd like to hear the sound of that cam/engine combo!
I'm putting together another tunnel rammed engine for my present project; a '63 Falcon gasser. Using a 454 with Weiand oval port tunnel to match up with the Edelbrock oval port heads, and twin 600 cfm Holleys. I put an 8.8" Ford in back with 3.73 posi, to make it more enjoyable on the street, but still make it run good at the strip. A Super T10 inbetween, just because I miss shifting a stick!

BigMo AHHHH !!! Nice, finally a hot rod with the TR setup....im putting together a pile of parts and such for the small block in my 30 Coupe, and after I get it broken in, im planning on that TR being thrown in...HELL YEAH.....nice headers, they Sanderson?

My KB pistoned 406 is 9.8:1cr. It punches way above it's weight. Stick to a reliable plan and your 355 will too.
I agree, not going to push the envelope......I will stay at 10:5 and be happy I'm sure.

F-BIRD'88 Buddy: While the summit cast pistons you are using are very good quality, they are a cast piston. You DO NOT WANT TO experiment with DCR theory and seek maximum compression ratio or the limit on your pump gas with these pistons. You want to stay well within the real world limits of the fuel you are using.
You will make excellent horspower power at a reliable practical 10.5:1cr in your engine.
The real gain of pushing it further is VERY VERY small. You will not go faster. Your luck will run out.
Its just a matter of time.
All you will achieve is busting up a perfectly good set of nice pistons and cylinder walls.

How long do you want to go fast till the luck runs out????

The usual typical failure mod when High speed detonation occurs is a broken top ring land, usually right near the intake valve relief.

A more expensive forged piston just takes longer to fail. If it does not break, it distorts the ring lands and scuff the cylinder walls. The engine if *&^%ed either way. It takes about 5 seconds for this to occur @ WOT and YOU WILL NOT HEAR IT.

On a high performance engine that will see WOT running pay close attention to the recomended top ring end gap.
Especially on a hyper piston. More heat load requires a larger top ring end gap. Horsepower is heat load. more heat more often/less time to remove it.

These pistons are Heat efficient.... translated that means the engine often makes maximum power with a bit less than typical spark advance. KB says about 2 less is typical. It also means the rings gap needs to be generous.

i was under the impression that this is true. The Edelbrock Street tunnel Ram has larger runners than the Weiand Hi-ram.

I had the Edelbrock tunnel ram. The runners are quite generous.

One day i am going to do another one with a tunnel ram.

That's almost exactly what they said. With this cam and the TR and a self imposed shift point of 6800 I'm not going to be maximizing the airflow of the intake and cam anyways, so they suggested that these heads would likely make less power at the top for a more rounded motor down low. He thinks I will be very surprised at how much torque this will make. And as anyone who follows my occasional drivel on here knows , I love bigger and generally subscribe to more is better theory. It was almost painfull not arguing with the tech guy when I ordered them lol.
