If you ever looked at his rebuild for his 304 C all the pics showing the combution chamber of the block is all scrambles like its some kind of wied IH porn

an example

thats because Mr. C. has left STRICK instructions to keep most of what he has done to that motor a secret, the porting and head work is hush-hush, and oviously he did some piston work as well..



only a few people know some of what has been done, and I think only 1 or 2 know all, I don't even think tommy knows it all.


No one will say what the actual displacement is either..... so it 304 ci :D

whats the big deal about that:confused:
All pistons are aluminum, but a skirt less piston weighs less. The down side is they will not last as long as a standard piston and will slap much sooner. But leave more room if your stroking the motor. I'm sure it will have a special contour for more compression with the proper squelch.

Weird IH Porn.. ROFL

:D

As Rusty said.. some things are still secret. :D

... and longevity wasn't a concern when we spec'd it out.. this motor will never see 50k miles.. definitely not in this chassis (I highly doubt the rest of the Scout will last anywhere near that long)

Back to the shop to work on the new pullin' 392.. :D

I can understand Tom keeping his motor a secret but as far as the engine builder I just can't understand not letting the person paying know.

Thats the way I understand it please correct me if I'm wrong.

He's the only engine builder I have ever heard of doing that that sells to the public.

Well, it's better that I *don't* know.

I bought a motor, from an engine builder.

He told me it was a 304ci IH motor.

If it turns out the heads are ported, I didn't know.

If it turns out it's been stroked/destroked - I didn't know.

If the pistons are non-stock, I didn't know.

If it turns out to be a 392 that he ground the ID plate off and restamped 304, I didn't know.

If it's running a mushroom/solid lifter/roller cam, I didn't know.

etc.

All of which are things that'll bump me a class or two when racing.

But, AFAIK, it's a higher compression cammed 304, and legal for my class.

:D

Tom do you have Dyno numbers from the mystery block?
Not yet.

I have some DesktopDyno *estimates*..

I was going to put the motor on the engine dyno at the machine shop before I installed it last month.. but time got short.. so I just installed it and ran it.

Don't worry.. another friend finally has his chassis dyno up and going.

I'm thinking of heading down to Bozeman (100 miles, where the dyno is) to run the racer on the dyno after the new 4bbl intake is ready.

I'd like to dyno it with the 600cfm 4bbl on the 4-2 adapter and 2bbl intake, then re-run it after installing the 4bbl intake and try it again..

Tom...

I would almost pay you money to see the results from the above test.

If this is a "304" how can you have a 4bbl intake? Is it a grinder/hole-saw version or one of the $$special$$castings...?

:D :D

It won't be sheetmetal like I'd originally planned..

And it's not the modified 2bbl/4bbl intake I bought 2 years ago and GRT now uses for a door-stop...

It will be $$special$$.. though not the hole-saw/die-grinder that I was going to attempt myself, either.

Definitely like to see what the results are, though.

It *seems* I'm still stuck at the 5300rpm-ish level with the 600cfm 4bbl and the 4-2 adapter and the ported 2bbl intake. Same as I was with the 500cfm 2bbl Holley with the spacer.

Either the heads still won't flow enough, or the intake is the restriction.

I'm hoping it's the intake, of course. :D


Well then you should at least give us the estimate to tease us a little
:D The estimates I have set the mark between 350 and 400hp and the same for the torque. What that comes out to be through the slushbox to the rear wheels, I don't know yet.. a T19 would probably lose less.. but it's hard enough to drive with two hands on the wheel, and two feet on the throttle.

Interestingly, I estimate the 392 for my truck to make a few more lbs-ft (IIRC, in the neighborhood of 425lbs-ft) but a good bit less HP than the 304C.

'course, I expect it to do this on cheaper gas, too... and run well past 100k.

I know the 304 makes more power than the built 345 in my trail rig.

If any of you will be at RMIHR, you're welcome to take a spin... :D
