Sounds like I'm going to be happy with just a thorough inspection & going thru by our local machine shop, balance it, have one of you AMC guys to clean up the stock (mild porting) heads a bit, mild cam, new manifold (edelbrock air gap maybe?) & carb, good headers (headman?) modify the oiling systom & maybe the crank for an auto trans (then find a good one of those). Doesn't sound any harder than the SBC 383 "stroker" I was planing! Shipping company says The engine is due here this Friday so I'll have a much better idea what I have to work with soon. In the mean time I'll keep reading all the posts I find here on the forum, there IS a lot of good info here!

I've got that article but will have to find it. I think it was actually in CC though. And because iit was one of the dudes from American Performance and not some CC or Hotrod tuner hero it actually made what an AMC V8 should make without going backwards like seems to be the case when either rag has a hand in a build.They are hard headed, including Glad.

That engine in Car Craft is Bill Tichenor's engine, a Marketing guy at "Holley". Bill is a cool guy. I remember teasing him at the Street Rod Nationals what carburetor he would put on it and on how nice that engine would look with an Edebrock Intake and Valve Covers!

Cloudy, Phat actually provided the article on Bill Tichnor's engine. I still have to find the older article with the 500 plus hp 401 Spirit. Keep in mind that all the hp figures bandied about are for comparison only. Depending on the dyno type used and the settings the figures are a reference and in some instances no more reflect accurate reality than Britney spears and good judgement. Not having built an AMC engine yet I can only comment ( despite the lack of awe for CC or HOTROD controlled AMC builds ) that from archiving stuff over the years and from experience with other engines that some of the stuff they come up with really has me scratching my head in wonder. Tichnor's engine seems to have been between him and J.T. Payton and the numbers based on the sketchy information provided don't seem at all unreasonable, agin from the dyno readout as a reference standpoint. The cam used has fairly mild specs ( though with a stout lobe separation angle ) and depending on which casting they chose I'm wondering about the valve sizes they went with. Seems like Ken Parkman's experiments with later castings ( 993? 502? 090? ) indicate that if you go the big valve route there has to be alot of complementary unshrouding and bowl work to really take advantage even with later CC's that don't crowd the intake side like a 291 casting does unmodified. However, J.T. Payton is a respected name in AMC circles. I thought he was connected more to Jeeps though. Given the stated goal of hooking up fuel injection and maintaining driveability and looking at the average torque figures this engine wouldn't have been a bad base both for an Engine Masters challenge but likely kicks serious butt on the street with that broad curve. Wouldn't be a bad basis for a strong autocross ride. All in my opinion.

Tom, Just curious, what casting number do you have on your heads? Post this information if you'd like and you can get some valvetrain opinions...as your options will vary a bit depending on what heads you've got. Steve

Steve,
I bought this "sight unseen" from my Fed-Ex guy who has, like me, been a hot rod VW guy (don't laugh my VW powered glass buggy runs low 11's, high 10's on carbs) plus, he's also been an AMC guy for years & years. Anyway the motor is due here Friday & I'll post all the numbers I can find on block & heads. Tom P.S. was at Summit in Reno (Sparks realy) today & bought wheels & tires for my '64 wagon. And from their "sale" table a new Edelbrock performer manifold for a bargan price! My FIRST 401 hotrod part, I'm SOOOO proud!! Edited by bughappy - Jun/18/2009 at 7:05pm |

Performer is a pretty nice stock replacement intake manifold, more so at a bargain price.
If planning a stall converter and some gears, the Torker works really well on an AMC, imho.
