409 blower intake

[MRHP]

Block is finally back, bore is done along with line bore. Nothing further to report.

Ordered a SFI 21 pound steel flywheel, and a flex plate today. I want to keep my options open with the motor. I think my guy said the bob weight is in the 2190 range. Is that decent? Any downsides to a 21 pound flywheel on this motor? I did not think so, but what do I know.

 

[Ishiftem]

I think that would be just dandy.

21 pounds sounds like a happy medium between the aluminum ones that are what?? 14 pounds or so and the usual 30 pound steel ones.

The aluminum Hays I had on the original 409 (now the 383 in the 79 Camaro) is 15 lbs.

I believe I have a 29 pound Hayes on my 474. That spins up pretty fast.

Intake is getting blasted today. Man this motor has been dragging out. My machinist is damn good, so I guess I don't mind waiting. Quality takes time I suppose. Just wanted to give an update as it has been a while.

 

[Don Jacks]

Good to hear!I was beginning to wonder what the hold up [EXCUSE] was.

 

[MRHP]

Since I don't have a willys or a 55 yet there isn't a big push, but I still would like to get it buttoned up pretty soon. The guy let one of his employees go a month or two ago, and that has slowed production a bit as well.

 

[MRHP]

Got a call today, sounds like the blower motor is getting worked on again. Mocking up and measuring chamber volume, and such. Yea!

 

[MRHP]

Short block nearly done. Compression is a staggering 7.7 just right for some boost. Full steam ahead.

I'm working on your 55! I would gladly dump the 327 for the AWESOME blower motor your building.

 

[MRHP]

A 55 would be nice.

 

[charlie rogers]

nice build! I will be watching and taking notes for my blower build.

 

[MRHP]

I just ordered the pushrods today. Manton .145 wall 3/8 diameter. Seems kind of thick (heavy) to me, but that was recommended by a few sources. Should be here in 2-3 days. Getting closer. Time to assemble the blower drive,carbs and such, maybe tonite.

 

[Iowa 409 Guy]

Should fit right in the altered.

 

[MRHP]

That's where this is all heading Dave. Hope it is a decent car. Right now it is a complete car that was raced last year. Chassis is not certified, but if I was told correctly, as long as I am 10.00 or slower, it should pass tech. He has had no trouble at Kaukana Wisconsin (WIR ) with it, or at Union Grove Wisconsin. I would assume I would be OK as well. I think he said it is due for seat belts. Can't wait for Saturday.

2500 pounds and 500 hp puts you in the 9 second range so I am sure you will be going faster than 10.00. Better read up on what is required to certify a 9 second open cockpit car. Maybe the car would certify or only need minor updates. It sounds gay, but knowledge is power! Is the car in southern WI?
