I have heard all kinds of claims on what this combination will produce as far as HP. I was wondering if anyone on here has built one like this and dynoed it? I have all the parts to do it with just dont know if it will be enough power for what i want to do. Thanks for any thoughts Dean.

Its been 40 years or so but I think that is the combo my neibour used. For some reason he found he had to use double head gaskets. Man would those things pull.

I rebuilt my 1945 case Multifuel last year with an LP head and pistons. the pistons are differant so you need to have yours modified or get aset of Lp pistons this will bring you up to 8 to 1 compression and about 80 HP Since i did mine it really pulls strong. I hope to do more to it this summer to get all I can from the old tractor at the pulls. I hate to lose. I also set the RPM up to about 1530 RPM that helps a lot. You can get a laser tackometer on ebay for this. Email for more info. [email protected]
