Re: Lion Speed Head
But you have to remember that Henry used iron heads as orginal equipment.

Re: Lion Speed Head
[QUOTE=johnsor;863064]I like my Model A mostly the way it was originally designed, double clutch and all
You use the clutch to shift? I learned to shift my first Model A without using the clutch when I was 16.

Tod Buttermore
Has cast and machined heads for the 351 Ford Cleveland engines. I believe he casts and machines the Snyder Model A heads also. Some Model T parts too. details here and several other sites, HAMB, early V8 etc. http://fordbarn.com/forum/search.php?searchid=3877098 User name on Model A FB is Tod other user name on HAMB I have seen is 427designer See post number 9 and below where Tod introduces himself on HAMB. http://www.jalopyjournal.com/forum/s...d.php?t=616056 MORE... https://www.fordbarn.com/forum/showthread.php?t=135011 Last edited by Benson; 04-23-2014 at 07:49 AM. |

Re: Lion Speed Head
Purdy, Yes, 13 more HP as indicated from my dyno. (You can feel 13 HP when you step on the pedal!) The head is a 6.5:1 compression ratio if installed on a stock bore. My test engine is over-bored .080" so it is just short of 7:1 actual compression ratio...if my calc's are correct....sometimes they are not!

Re: Lion Speed Head
Thanks Dave, I don't doubt your calculations. I was just wondering which head to buy, 6 or 7 to one. Charley once told me that the counter bore was plenty deep to mill his heads to 8 to 1 or more .

Sounds like your experimenting is coming along good! If a guy 'insists' on using the original mechanical advance system...you will have to go thru what you have been experiencing with this lsh 111 version. I got one of the first copies of this version and ran it for last 6-8 years. I ended up where you may be headed, i.e.- electronic ignition ! Fire it up with retarded spark as per usual, then pull lever down and FORGET IT ! My B was built very sturdy .030 over with popup pistons with this head. I figure 7:1 and better. It ran VERY strong with 2 81s. I should have left well enough alone,eh . But, a guy can not do that, so one of the guys here is now 'bragging' about how well it runs on his engine ! BTW...for those who 'object' to the tooo modern look of some elect dist, I put pertronic elect module setup in my dist and never looked back. Absolutely trouble free. Only wish it had automatic advance, as I believe that I'd enjoy it even more ! |

Re: Lion Speed Head
I run Mallory dual point distributors in two of my engines. You can get centrifugal advance without going to electronic. A Pertronix Flamethrower coil gives plenty hot spark. I'm a shade tree mechanic and prefer points ignition. Twenty five degrees advance, electronic or points should work just as well.

Re: Lion Speed Head
I'll wait untill I get ready to build another engine before I look in to ordering a head. I see now that I mis read Daves post and the heads are now available only in .6.5 compression. Thats better and should be more user friendly than the 7.0 The increase in horsepower is impressive. If I can feel a nearly seven horse increase with a C or F3 head, you bet I could feel a 13 horse increase over the BF 5.9s

Re: Lion Speed Head
Well, good question ! IMO, same question asked differently is...how do you fix a design flaw in a piece of equipment ? The answer may be what was done, i.e.- make more versions , until you 'get it right' ?
Seems like a decade ago or less, when putting together the B that I've had in my A, I had discussions with people about buying a head with certain characteristics. While looking/talking about lion head, was told by those who 'claimed' to have bought the first two versions...don't do it. As it turned out, the third version just came out and good was heard. Turned out to be true. I've also heard over time that IRON head makes power, while aluminum...looks good ? Well, if iron makes power is true...this third version should make plenty power at 53 lbs My third version did positively add to my B. I have intentionally not added the 'things' that were said that were wrong with v1 and v2, as I did not have direct evidence. Those who have / had them can better address that. |

Re: Lion Speed Head
Probably the best on could to improve a LH1 would be to equalize the combustion chamber in volume and shape for all 4 cylinders. This may not be easy. The LH3 has CNC cut combustion chambers while the LH1 chambers are "as cast".
