Six Cylinder Drag Vehicles / Little Update On My 6 Cylinder SDRA dragster

« on: May 10, 2014, 06:50:37 PM »

Thought I might post an update on the car as I have not been on the thread much this year. I have not been able to run the car since last Oct. Medical problems have kept me out of the seat for a while. All is looking good and mending well and hope to run the car at our June ANRA Nostalgia race in Bakersfield, CA.

Made some improvements to front end setup by adding some friction shocks and having the front tires skin cut to get a better roll out. The tire/wheel roll out was .155 & .125" out of round when we started and now the roll out on the tire/wheel are .015 & .018".  Should roll a lot smoother with very little wheel hop.

Pulled my 194 Small Chamber head and cleaned up the ports, installed 1.84 Int & 1.60 Ex valves and milled .060 off the head.

Built a pair of 3 into 1 collectors to replace the zooms, They are a little shorter than I would like but should work fine.

I know where your coming from on this big of bore. Know anyone that has done this with the water jackets that I can contact?

It looks like a lot bigger job to pour fill a 250 L6 than it is to do a SBC V8. What say?

OK guys, now that I know the block can be bored to 4.00" with it pour filled has anyone done a 4.00" bore on a Chevy L6 250 block with the water passages in the block still open.

I really would like to keep the cooling system for the whole motor if I can and pour filling an L6 motor is not as easy as a SBC V8. The cost of sleeving the motor is out of my bracket.

This motor will replace my existing 194" L6 with a 266" L6 in my vintage dragster.

Dolmetsch -- Have you ever bored a Gen-3 250 L6 to 4" (with or without block file)?

The main reason, it easy to find 327" forged pistons with a solid .125 dome that milled down to .040" will provide 11.5 CR with my block -0- decked and head milled .060". I an unable to find 307 piston in cast or forged with a .125" dome and FT 307" piston yield only 10.6 CR.

You know me, I've got to be different. Most other would drop a chevy 292, GMC 302 or a Ford 300 in and go have some fun.

tylercrawford -- I agree with you that it looks right with the multi carbs and I am able to run

two (2x4) adapters on the intake I am currently running (not in pictures) so I could run four Holley 94

carbs. They make about 155cfm each for a total of 620cfm and this motor will need all of that plus

some.

For sale is a Vintage Clifford High Ram 6 cylinder 3x2 Intake manifold. It fits all Third Generation Chevy 194/230/250/292 6 cylinder motors without the integrated intake.

This intake is in like new condition and looks like it has never been run. There is a casting flaw in the left hand raised “CLI_FORD”.  The right side raised “CLIFFORD” is as it should be. There are no cracks, repairs or thread problems. The letter casting flaw has no effect on the intake operation.

This intake was built to run 3 Rochester 2G carbs. The bolt pattern is for a large base 2G Carb, but you can get adapters to run the small base 2G carbs.

Shipping should be no more than $18 FedEx Ground. If you PM me your zip I can give you an exact amount.

PRICE -- $250[/size]

Dolmetsch -- Ya Don I was going to go the 307/250 way but because of the 11.5-11.75 CR and the 7500 RPM I would like to use forged pistons and I have not been able to find any off the shelf 307 forged pistons. Also I really like to go outside the box and run something that is a little different. I think this motor if it can make 270-280 HP will be able to run with the Chevy 292/ GMC 302/ Ford 300 and even if it can't it will be a heck of a fun ride. Hoping for 11.50-11.75 ET.

masracingtd1167 -- Thanks for the good word, it is like all drag cars (a never ending project).
We are just getting a small group of SDRA dragsters going out on the west coast, 3 in CA, 2 in AZ.

Six Cylinder Drag Vehicles / New 6 cylinder Motor Idea For My SDRA Dragster

« on: September 21, 2013, 07:48:15 PM »

During the off season I want to put together a new motor for my SDRA dragster that has a little Chevy Gen 3 194" motor currently.

I am looking at a Chevy 250 block pour filled to within 1" of the deck, Bored .125 to 4.00 for 327 forged FT pistons, O deck the block, CR about 11.50-11.75, Clay Smith cam about .550/.550, Small chamber 62cc head with sbc 1.87/1.60 valves, After market 4bl intake with a 600 cfm carb. Will run water in 1" of the block and all of the head. This setup will make 266" and I hope 270-280 HP.

Just a note that we can not run slicks in the SDRA dragsters, only 6" DOT street tires so it helps to keep the bottom end power under control and make lots of top end. Dragster runs a PG with 8.8 Mustang traction lock and 3.77 gears.

What say out there, comments and any past experience with this type motor build? This is a home build motor with cost to be reasonable.

Denver -- Thanks for all the information, I will pass it on to my friends.

Don -- The only reason they are not using C4 is that both have nice race powerglides to use.

Thanks for the information, do you know what the flexplate # is? I found a TCI # 890-529625 at Jegs and Summitt for $139 and a couple on Ebay for the same price. I think you should be able to get the correct unit SFI for a better price.

« on: September 06, 2013, 03:41:53 PM »

Looking for some help on a motor/trans combination. It will be install in a vintage style HAMB dragster like I have.

Is there an after market adapter bellhousing that will mate a Ford 300" 6 cylinder motor to a race PG trans? What about the flexplate (size & teeth).
