I haven't read the article yet just the pictures....

There playing with the rambler again. I guess they must have fixed the 360. This time they put a hogan sheetmetal tunnel ram on, plumbed it for nitrous and put it on the dyno.

Before the hogan intake made 465hp and 431 torque

adding the hogan intake 474hp and 440 torque

a little hit of spray I think 175hp...it made 649hp and 638torque

a big hit of spray I don't know how much more 695 hp and 667 torque

I guess its cool there playing with amc's...except our secret is out and prices are going up.

Bart I thought I put this in the general section but I guess not...ps thanks for the karma points...

wow only 10+ hp/ tq for the hogan? same rpm? thats..... kind of weak id think

but what do i know? im just a poor sob

I don't know if thats weak or not. My opinion its a low rpm engine as far as your typical tunnel ram engine is concerned. I'm suprised it didn't lose power. I think there must be some good engineering going on there.

The rub is the hogan intake for the general public must be around 2500 to 3k. I think for the general public to run out and buy one would be a waste of money.

I don't know I've never used one,,, I just see clunkers and beater camaros with tunnel rams running 14's that would probably run 2 seconds faster with a single 4.

That Hogan intake that the guy at Car Craft is running is just total OVERKILL.I mean Mike Luke don't even run something like that or DRAMC Rob

thats why i was wondering what rpm it was at. i havent read shit on the motor so i dont even know what the inerds are. i figured that they (car craft) somewhat knew what they were doing and the had a somewhat correct sizing on it.

how high are they spinning it anyways?

Well put. It's a pretty good gain considering the engine itself, but the "gain per $$" isn't worth it IMO. Hogan is a BIG dollar piece.........yes, upwards of $2500.

The engine has a "stock" 360 crank, offset ground, w/ Scat 6.00 chevy rods. The build up was in the January '06 issue, and was worth several pages of discussion by many of the spreadsheet engine gurus.

ah thats why i never paid much attention to it. wait was this the one that they welded on the rods? wtf was that all about?

so they are using a hogan tunnel ram on a engine with a stock 360 crank? (how much was it offset?) what about the heads? might have to pick up the issue for a laugh

They welded the rods because the SBC rod is narrower on the big end than the 360 rod. While I understand why they did it, I do know that the SBC rod has been used on those cranks before, without the larger side clearances being a problem. I don't know what haeds they used with the Hogan intake, but for the dyno runs in the article, it had Edelbrocks. There was also a pic of the engine with Indy heads and a sheet-metal HLR intake, that they never referenced. They didn't mention how much they actually offset ground the crank, but they say it's 370 inches, and with the bore they used, the math says they offset to 3.50 stroke, which is +.060 stock stroke. If you look past the welded rods, it's not a bad build-up. It would have been cool to see a comparison with some mildly ported stock heads though.

Back to the welded rods..........in the same issue of CarCraft where they covered a 401 build(actually the one that was on HorsepowerTV years ago), the same shop that built this 360 did a 383 Chrysler stroker using big-block Chevy rods. They were concerned because they are narrower than 383 rods, and the had excessive(didn't give a #) rod side clearance. They decided to assemble it that way, and after dyno pulls, reported that they had no ill effects from it. I still don't understand why, with the same situation on the 360, they welded the rods ?? Anyway, now that there are good rods made for the 290/304/360, there's no real reason to weld up SBC parts.

My real intrest is how long the block and crank will live at the 600+ horsepower level.

They're spraying that thing? Almost makes me think they're trying to blow it up.

Those fuckers at Car Craft have an endless bank account,thats why they can restore a car,slap on some racing rims and tires and wait 56 fucking issues before they drop in thier mega dollar engine they built 567 issues earlier.

not too sure i would trust a welded rod but what do i know. probably ok for a hot little street motor. id rather have a little too much side clearance then go through all that crap. but then id have gone with some crappy cat rods instead of what they did
