273 - many years ago, 10 or so, some entered a 273 in the Engine Masters contest and they did an article on it. It only made a few test passes and didn't compete. Have you ever run across this article or was I dreaming it?

Didn't they have a head gasket problem?

This is all too familiar. There is a picture of a 292ci 273 engine with 8 sleeves taken in 2010. It has Indy/RHS-X heads, Jomar girdle, stock crank, Ford rods, roller rockers, push rod oiling, Comp solid roller cam and lifters, wet sump oil pan, HV pump, oil crossover (hidden by the paper towels). I had to drive from Morton, IL to Melling to pick up the sleeves and bring them back to be installed. It had to be re-sleeved because the first set of sleeves were offset and the valves hit the cylinder walls.

The cylinder head had to be repaired because the #7 exhaust port cracked and was leaking water during the dyno runs. I had three of these heads that had the #2 or #7 exhaust port with very thin casting in spots.

See post 109 in this thread.....I believe this may be 273 engine from those dyno sheets.

Is 426ci 360 a small block?

I sleeved all 8 on that block..... twice... lol

Yep, you did a good job. I had to make a run and fetch the second set of sleeves while you cut out the first set. I remember the day!

Off hand, do you remember what magazine (issue) the engine was in? I have it somewhere but not sure where to start looking. Thanks
 
Have any of these magazine builds matched the dyno numbers at the track? That'd be a fun comparison to see.

I suppose you could compare mph to weight but you’d introduce way more variables unless you used the same car for all tests. We all used the same dyno for these tests which was a much better comparison of combos. We were within 2-3% of the dyno we normally used with our big block builds vs. Comp Cams dyno so I’d consider it very close.

Interesting, but how do you not change cam timing for different cylinder head configurations?
Click to expand...

True but really what percentage of people would, yes top builders or someone trying to get most out of a combo, but you average guy gonna run something like an xe285hl or equivalent from other companies in their street strip car no matter what make, engine, size or parts on it.
 
What!!?? They didn't change the timing ...........

Timing and fuel don't matter it needs more AIR!
 
Here's an interesting engine: http://wright-here.net/files/articles/phr_1109_sbo/phr_1109_sbo_ocr.pdf

Unfortunately its not a mopar but fascinating just the same. They made 1.37 HP per cube with only 195 cfm peak flow. They made 2.2 HP per cfm truly remarkable when you think about it.

"The intake port is way smaller than the original. , think the factory was 152 cc and now it's down to 145 and it's much higher. It's got a small cross section of 1.91square inches]." Final flow numbers ended up around 195 cfm on the intake and 170 on the exhaust. Though not huge peak flow numbers. he claims they were almost at those numbers by .200-inch lift. Just perfect for limited camshaft and rpm range applications."

And they did it with an Edelbrock carb........:lol:
