Time is running out for a new best

[pittsburghracer]

When I built this engine (Indy headed 422 small block) I never thought I had a chance to get it into the 5's on an 1/8 mile hit but I've been oh so close. It went a 6.004 and three weeks later I ran a 6.003@113.27mph pass. Its been a target of mine to make it into the 5's while still running a solid lifter cam. It will be coming apart after 9 days at The Halloween Classic at Norwalk Ohio in two weeks. I will be racing Sunday, Wednesday, Thursday, Saturday, and hopefully Sunday so with some good weather I may get my chance. Its gone 9.40's in the 1/4 mile but without the roller cam its laying down some.

9.40's with a small block? You're flyin'. Good luck at Norwalk!

 

[pittsburghracer]

Thank-you sir.

Thanks guys. My Son has been after me for years to put an air pan on it so I made one up and jetted up 4 sizes (alcohol) but we had some pretty hot humid air last weekend. I downloaded the info from each pass but didn't read it yet. It did seem to make the car more consistent over the 3 day race.

I like the pan idea. Might have to make one up myself.

Hopefully the fall weather will get you the 5

I was going to say you can buy a pan already done. But it wouldn't have been as cool as what you made. I like it.

Good luck and good air!!!

very impressive. I'd love to hear more, perhaps more pics and more details?

Hey John, I’m just up the road from you, in Clarion. I’m doing a W2 headed 422 smallblock now too. Did you build the engine? Love to pick your brain on it.

 

[MopaR&D]

That air pan might just make enough of a difference, I'm guessing the scoop was just open to the engine bay before? Best of luck, AWESOME car that pic is glorious lol.

Yes I do all my own porting and engine work except block prep and a local shop does that for me. I'm 61 years old now and when I as 20 years old I waited 13 months to get an engine built by a local mopar expert. I told him the day I picked it up I would never wait on an engine again, and haven't. My last 408 build started out with W2 heads but they were the castings known to crack, and they did. I had a real nice set of Edelbrock heads with 2.08 valves I ported and ended up going 9.60's with them. I sold off all my W2 stuff but I loved those heads except for being cast iron.

It probably would have but between jetting up and the hot humid weather all it did was tighten up the ET. Looking for some GOOD air. LOL

I know what you mean about the W2s being prone to cracking. I’m keeping my fingers crossed that mine don’t. I’ve already sunk a ton of money into them and still need to find shafts and stands. Maybe I’ll drop by sometime this winter to chew the rag a bit and check out your racecar.

My hands were kinda tied on this one as I bought it as an unassembled package deal
59 degree R3 block (4.100 bore)
diamond 12-1 pistons
Eagle 4 inch stroke, Eagle H beam rods (422 cubic inches)
360-1 heads that had some work done but I redid them with LOTS of flow testing
Indy intake that I ported
640 solid lift cam with Hughs EDM lifters
850 alcohol holley carb
70 Duster 2750 pounds race ready
Powerglide with 1.98 low gear
4.88 rear gear, 14-32 M/T slick
1 7/8 Hedmen Headers

Anytime after the 1 week of November would be great. I still have Norwalk to get past and I almost have my 572 done for my small tire Duster I am building. I may try to make a couple of NA hits before winter sets in.

I'm not sure what the back portion of inside your scoop is like. but you may want to make a curved deflector so air is not trapped behind the carb. You want the air to flow in the carb opening like a rounded elbow.

That sounds like something worth trying but it will have to wait till a Winter project. We just finished my Sons car last night so that's a priority for me getting him ready for the Halloween Classic. Thanks for the suggestion.

I have some w2 heads, but have never heard of the cracking problem. Do you remember which number castings are prone to cracking? and where do they tend to crack?

 

[SSG_Karg]

The earlier heads had a tendency to crack at the outermost head bolt holes. The later castings have ribs around the holes to add some strength. Same casting number, different part numbers.

thanks. any chance anybody has some pics of the difference.

I couldn't bring myself to scrap the heads so mine are still leaning against the wall of my shop. I will try to snap a few pictures but they cracked right below the lower bolt holes as posted above by another member right by the W2 casting. Mine were the econo heads that flowed 260 cfm@.450 lift then dropped off. I had them around 308cfm with the stock 2.02 valve.

Wow, that’s moving some air with a 2.02 valve. Mine only go 306 cfm at .600 lift with a 2.08 valve.
