Engine Masters Challenge, CHI Heads, and Cobras

[Manowar]

Post # 19 Manowar: "Those were original Ford deck sizes, but I'm not sure which vehicles they were in. I think the 9.2 was used in passenger cars and possibly the Pantera, which had Cleveland heads.There are many more Windsor experts on the forum than I."
This doesn't mean I don't know the difference between Cleveland and Windsor. Water crossover from heads, distributor location, thermostat location and deck height-I only stated that I was not clear what vehicles they came in. Yes the Pantera had a Cleveland (9.2 only) as did many Mustangs, Galaxys, Cougars. The picture I took which is posted above is our 9.5 Windsor block with CHI's heads-not Cleveland heads and not 9.2 deck. I also acknowledged that I was not expert in this area. I would have hoped for some instructional clarification rather than a judgement of incompetence and mistrust. Post #24 Commander:"I'd be a liitle leery buying blocks from someone who doesn't know the difference between a Cleveland and a Windsor 351." Post # 25 Kevin: " I agree about his not knowing 9.2" was the deck height of the 351 Cleveland, that is a little surprising."
Post # 21 Commander: "Pantera had a full blown Cleveland engine in it, block AND heads. The 9.2 was the Cleveland block deck height. 9.5 was the Windsor 351 block deck height. The 8.2 deck is for 302's."Agreed and understood. I was informing olddog that OUR blocks were 8.2,8.7,9.2 and 9.5-all Windsors. I do not know the origin of the 8.7 and hope to learn that here.
Post #24 Commander: " I don't think it's right to back out the little steam tunnel (which yours doesn't have by the way) since for most of the the length of the cylinder, it's .130+.125=.255 vs your .250 minimum. I think you're making an airplane hangar out of an ant tunnel." You're entitled to your opinion but here are some facts. We intentionally designed ours to have smaller water jackets and no cross-water feed between cylinders for strength. We figured-out the block didn't need them. The Boss blocks exhibits larger water passages which means less parent material.
Of the 150 or so of these engines we've built, we never had a complaint or warranty claim of overheating or running hot. Also please remember, our max bore size is .075 greater than the OE spec that you're providing the math for. At that size we're .180-.200 parent material in most places. I consider that a significant factor-not "an ant tunnel".
Post #25 Kevin:"I don't know who is casting those blocks for them, but I would be willing to bet it is an outside supplier." The FRPP site states that it's cast in their own foundry and machined in-house.


Finally, I apologize to DavidNJ, the originator of this thread. It was never my intention to divert his question. I prefer that we all be pals and share info.
