Yup, somebody pays him...
They stated it was a stock rebuild.
I saw some of it.
cast piston 360
1.88 J heads
218/228 448 lift summit cam cut on a 114 LSA - that will help...
Stealth intake
POS 600cfm from feed carb. Looked like a summit carb
Made 314hp/380tq
IIRC, both the ford/chevy had forged pistons in it and used a holley carb.
They also said that the heads used up to 72 had 2.02 valves and after had 1.88... ummmm yeah OK!
To call them retarded is an insult to people afflicted with that condition.
Whats wrong with weiand stealth intakes? would like to know since I have never had any experience with them but have been considering getting one for my 360.
Up to 1971, the 340/360 heads sis use 2.02 valves. Would you like a picture? I have a set.They also said that the heads used up to 72 had 2.02 valves and after had 1.88... ummmm yeah OK!

1.5 tube? Humm, I never ever seen a 1.5 tube header for a Mopar. I swear it was a hooker comp. header they spoke of which would be 1.5/8Yup,I watched it. 360 had stock pistons,rods ,1.88 heads. Small 1.5 inch headers and a small cam about .440 lift. Weiand hi rise intake. 314 h.p and almost 390 lb/ft torque. Very flat torque curve and nice steady h.p curve,lots of area under the curves. Nice simple stock motor that idled stock.
About what I expected. They took a stock motor,cammed it and put a crappy intake on it.
That's what I thought they said. Hummm, now I'm gonna have to go back and watch the recording. (Damn it!)I forgot about the 1 1/2" headers with 2.5" collector... they helped.
BUT, a 1 5/8 with 3" collector would have been better.
Not a fan of the Holley 2 part carb though summit racing redesigned it. How well it'll work over a good 4150 dialed in is another story. Given a good 4150!They stated it was a stock rebuild. Especially with a pathetic 600cfm carb. And the fact that oiling thru the rocker shafts confused them.
Ok. Don't shoot me, But what would have been a good build for a 360 and why. The parts needed and the mods to those parts. Curious here.
Yeah, that was the impression I received. I thought in subsequent shows they were going to start going more radical and see how much the could build into the engine. Maybe I'm wrong.
380 torque for under $2500 ain't too bad though. Not trying to defend those two buffoons, I'm just saying...
I saw the build and it was pretty lame. Stock heads, stock type dish pistons, stock crank, stock rods, crappy carb and a Summit cam.
Most every HP rod I've ever seen is the floating pin style anyway.

WHOA! Letting the dogs out on that one now aint we? Lets set up some parameters and have at it or well have a list of **** a mile long. LOL!
Block - stock minus overbore
Heads - OE 360 small valve
Cam - builder choice
intake - builder choice
Carb- builder choice
Ignition- builder choice
oil pan - oe
Cam drive -oe
Valve train -oe
Fuel- 93 stock fuel delivery. They just use a block off plate for the dyno.
pistons- builder choice
rods -oe
etc
etc
Up to 1971, the 340/360 heads sis use 2.02 valves. Would you like a picture? I have a set.
I agree with the second sentence.
The stealth is a good intake IF, and that's a big IF, you know what to do with the carb and jetting requirements.
Locomotion (Myron) knows the issues with the intake and I believe he's posted his findings here before. The carb generally can not be jetted in a normal fashion. You have lean/rich cylinders running a std jet set up. I had the same issues with one that Myron found.
POP quiz, who else use's a system like ours?
Rockers on a shaft?
I would also like to know why it is a "crappy" intake. I have one and plan on using one too.
anyone catch what the compression ratio was on this thing?
also did anyone else know they weren't 2.02 valves before the measured them? :thumbup:

Block 360 + .030" over
Heads stock, ported, valves with back cut, seats on exhaust pushed to get as much diameter as possible
Cam MP 340 reproduction .444" lift 268/276 duration Seat to seat.
intake any decent dual plane intake, with the plenum divider milled down to 3/8"
Carb 750 CFM pick your poison
Ignition stock with MP orange box, and a rebuilt distributor, set properly for the air gap.
oil pan stock, checking pickup tube for proper position. ported oil pump mating surface to rid the passage of sharp edges. Filter surface removed from block and more/larger holes drilled to avoid restriction into and out of filter.
Cam drive double roller, if possible, a "used set" from a local racer so it is "prestretched", and degree the cam
Valve train stock, with "banana" grooves cut into the rocker shafts
Fuel pump gas
pistons hyperuetectic, for expansion stability with the strength of a forged unit.
rods stock, side polished
exhaust headers, 2.5 collector, flowmaster, 2.25" tail pipes.

There is a large thread on here somewhere when we were all ticked off about it....the guy used a die grinder on the sealing surfaces of the block and, as already mentioned, torched the little end of the connecting rods!
Stock compression. Likely no better than 8:1.
Budget build, yes, I know there are better available, but the combo above should find 400hp without too much problem.
