Engine blueprint PLAN crazy daily driver setup.
#12
Well, i came up with some other combinations, and i came up with this real street, daily driver, stroker small block, combination. Tell me what you think.
Dart block
DECK: 9.325" BORE: 4.175"
RADIUS: 1.914" STROKE : 3.828"
ROD LENGTH: 6.OOO" ROD RATIO: 1.567"
PISTON: 1.411"
Well i wanted to do this with a 6.1 or 6.2" rod although the 9.5" SBC block went missing and now they only have the 9.5" tall deck 351W i might end up using. ihave a website with big bore motown and dart tall deck small blocks , now i wonder, is there a problem with the 9.5" SBC version, and why i don't see it anymore? With the large 4.175" bore it comes to 419 Cubic Inch. With a 4.030" bore it is a 391. If i had the 9.5" deck i would do this one:
DECK 9.5OO"
ROD 6.1OO" RATIO 1.525
RADIUS 2.OOO" STROKE 4.OOO"
PISTON 1.4OO" Non gas port piston.
This with the 4.175" bore would be a 438 CUBIC INCH.
.

To the spear heading of innovation. Still perhaps there is something i can do with cylinder sleeves to get a bigger bore size and more reliability in a small block daily driver and weekend strip stomper. Because now i find myself leaning toward more rod ratio closer to 2:1 . And i did that in a ford 'destroker' large bore engine, still has good displacement, with a great rod ratio. And increased efficiency because of the large bore to small stroke ratio. The same would happen with large stroke to bore ratio, they have an inherent efficiency gain and a limit, the lower efficiency 'square' bore to stroke ratio 1:1 has an inherent deficiency at first glance. However with great work more efficiency can be achieved than under and over square configurations with the correct technology, i would explain, although it would take doing first to explain it. Old Mech maybe i just need a blower, or hair dryer, oh, i don't know what i am doing anymore.
