Are you asking the weight? If so this thread probably will tell you more than you want to know.
Weight of 428 bare block??
Except for weight I would suspect the main difference between those two stock formula KC engines is the displacement. From being in his shop a few times I've seen that he does build certain formula or "crate" engines because I saw a whole row of identical 482 FEs wrapped up to go to Kirkham as needed. But, he is a custom shop and KC will make any number of changes in a engine build to suit what you need. |
Thanks that was a good thread on weight. So those two builds look identical and the displacement is the difference. I figured that, I was hoping for a discussion on the merits of plunking down 5k for the aluminum block?
Less weight is good.
Added potential displacement.
A stronger block.
The same metals, block, head, intake for the same expansion contraction or less potential leaks.
Although the weight is similar I wonder is the weight is effectively lower?
Cool factor.
I think Keith's crate engines are right on the money. Stout enough to be trouble free without added money where it is not necessary. Probably has great street manners but sounds good. Cam profile that has stood the test of time. I'll bet they have the carb specs dialed in pretty tight also. I am not sure making it "custom" has much merit if the HP and torque come in where you want.
