Jay,
Apparently I have not been keeping up on your project, and was unaware you had a solution to cutting the Cleveland manifold to fit your adapted. I have a Weiand tunnel ram I was planning on using, but would prefer to be able to swap between the FE & Cleveland. The FE installation would be much cleaner with the Weiand valley section removed and the standard thermostat housing on the adapter. If I tapped some threaded holes @ a 45 deg angle just under the manifold port sealing surface and ran a slitting saw straight through at the same angel (90 deg to the port surface) would it give enough clearance on the water jacket in the front of the adapter, or does the right side need to be cut up along the port? The thought being if I wanted to go back I could use button heads or Allen bolts to align the bottom tray, and install spacers the width of the cut. I believe I am #30 on the list, however I wouldn't mind being bumped to the end so everyone else is not delayed untill I figure this out. Is it possible to send me an electronic copy of the cutting template before I receive the adapter?  Auto Cad or other scalabel format would be ok if possible. Also, have you shipped any of the adapters with the water jacket removed? Please let me know what you think.

Thanks,  Pat.

comet2, I am fairly new to this and an not quite sure how the classifieds work. Can you confirm the adjustable rockers and can you send any pictures? Do you know what the combustion chamber volume is? I have a 390 with C8AE-H heads I am looking to do some improvements on soon, and would like another set of iron heads & parts if they are comparable. Also, where are you located and any idea on shipping to Kingston NY?

Thanks,  Pat.

I am new to this (and any other) forum, so if I am replying incorrectly please let me know. I have been looking for one of these for some time. I would definitely commit to 1, possibility 2 with the second one without the intake ports milled thru. In my early years I was running a 351C with a dual tunnel ram, however the engine developed an oil leak into the water jacket that I could not locate. The Cleveland was replaced with a stock 68 GT 390. The car has been sitting in the garage since 83, and I am working on getting it on the road again. The adapter for the 351C manifold would be a welcome mod. I will keep an eye on the forum for progress.

Thanks.
