I never said you were going to street race. I've had people get confused when I write/say "road racing". They don't understand road racing on a closed course which is what I like to do.

High RPM breaks parts, but boost will only get you so far before you have to spin the engine faster. If you want/need to spin the engine fast you'll need good parts. If you want to run crazy boost you'll hurt head gaskets and pistons first.

The Clifford and Engnbldr valves really are performance street valves. 2 and 4-groove locks are not good for high RPM engines. We had a guy here break an exhaust valve. You'll want good single groove valves and locks.

3500 RPM stall seems pretty arbitrary. How the converter is built will depend a lot on the cam duration. I would skip right to a 9.5" or smaller converter. Getting much stall from a larger converter kills the efficiency. It's false economy. This is why I listed the torque converter as a priority.

im not trying to be nasty but im not new to drag racing i was going to use and 9" and an 8" Converter i was going to use ENGINE PARTS NETWORK valves. do i need to cut the firewall out to make it fit.

It's alright. I'm not trying to lecture, just point out where the money is best spent and some of the pitfalls. Also trying to clear up road racing as opposed to street racing.

Engine Parts Network and Engnbldr are the same person. Ted has a good product, but it's not real race stuff.

If you want the radiator in front of the engine you'll probably have to work the firewall some. probably have to put the radiator in front of the core support. If you want an engine driven fan you'll almost certainly have to box the firewall.

i wasnt going to run an engine driven fan it robs hp not much but it still does, so i have piston, rods, valves, crank for a start ok so is this turbo too big a GT-K 450 Turbocharger, is this a good cam http://www.compperformancegroupstores.c ... HRY466Cams

There are exactly zero off the shelf slant six cams I would recommend. That looks like an interesting series of high-tech turbos, but I'd call Turbonetics before ordering anything.

Where are you located?

Sounds like a great buildup and you are not trying to skimp on important stuff. Low 11s should not be that hard if you are careful and creative.

The T60-1 turbo from turbonetics is a great choice and has been used to run the fastest doorslammer run yet - 9.85 @ 132 MPH. Call Turbonetics and ask for the turbo that (Tom and Leighton) Drake Racing bought for their Simca. I just bought the same one for my '68 Dart project. Describe your needs and they can customize. The turbo series you list could also work quite well.

EFI would be best, but a 650 would be a good choice otherwise. Search "turbo66valiant" on this site and you'll see the kind of setup you want to run.

Best place to get a high flow head is Mike Jeffrey (308-324-3576). He does not do internet.

I would set a redline of 5500-6000 RPM since you do not need more than that to make the HP you want.

Glad to hear you are starting on this project, and don't hesitate to ask more questions!

Best wishes,

Lou

I'm in Indianapolis, i just want this to be different, how many slant 6 dakotas has you seen, i saw that valiant and that exactly what i'm going for.

DO NOT BUY ANYTHING FROM CLIFFORD PERFORMANCE!

Other than that I don't think anyone here is lecturing you or think your out in left field. It will be difficult! However, I think your on the right track and Josh is putting in plenty of help. Frankly, I have to disagree with the turbo selection, a t-61 would be a far better choice or even better yet a gt35r (major money). Frankly I would look at a procharger, especially since you can get them off e-bay and stuff because so many big blocks and the like love them. I have no doubt you will have to go boosted to get your goal.
For street use I think 5% is stretching it with theose tires, but yes, road racing is very different than that Fast and Furious stuff everyone confuses it with, and no you will not be doing any of that. I will agree the stall seems high, but I don't know for sure becuase I'm a gear jammer. Don't use a Comp Cam call Erson at the least, get a new cam with very good specs.
Procharger with a carb is very doable, I perfer EFI for the money. I've been researching the higher dollar ones and honestly it's not quite double a carb. Yeah, it's more money, but you have to pay to play. Good luck, and skimp on the alky and go water injection.

If you need a head done get in touch with Mike. 308/324-3576

Dart 270 has a Slantkota street truck.

ok first off im only 15 so im just starting off, and the tires are drag radials, this is what i got so far, i will use k1 technologies slant 6 h beam rods with wiseco pro tru forged flat top slant 6 .045 overs, use a stock crank, have the heads and the block machined, use a erson cam, use engine parts network valves, snow performance water/methanol stage 2 gas boost coolers, use a 650 cfm Mighty Demon Blow-Through Carburetor on a offenhauser manifold, use a Turbonetics GT-K450 Turbocharger, with an intercooler with a Duo-35 Gunmetal BOV and a Evolution Wastegate and a Turbonetics Variable Boost Controller, have a pace fabrication motor plate. put Hughes 9'' 3500 stall that what i have so far... where can i locate a roller rocker arm, some lifters
Thanks for the help

i mean an all out drag truck

Glad to hear you are in Indy. There are a few Slant sixers around there, and you are not far from Clay City, KY where we'll have a Slant 6 race later in the year (usually Sept/Oct).

Rocker Arm Specialists is in the process of making up roller rockers. See the "For Sale" section for info on that group buy.

Sounds like a great buildup. You will have some work ahead of you, but it sounds like you're jumping in with both feet.

You might ask for Erson's 280/270 cam (yes, more intake duration) with 110 or 112 lobe separation for a turbo. Based on my research, that should work very well on a high output turbo motor. You do not want a big cam.

Happy building,

Lou

there one slant six racer that race around here and that is hillside six car iv seen it, its very deceiving and im in no big hurry to get the rockers yet. i have some another stuff to do to it.

That would be Howard Davis and his son.
