John, So are you back to the sbm intake straight adapted to the 350". For-going the b block center line up situation ? If so I am thinking you may have the setup. I talked to my machinist and he is worried about the small runners on the Chevy intake still being a restriction issue. I need to see one of the higher end sbc intakes now to look over runner sizes. ou: I can adapt the intakes no problem, but my intent was to provide a plate option that would help alot. But still be in the average guys checkbook range after all the parts(plates and intake new) were purchased. I have some crap to do tomorrow, but I need to give you call. If your just gonna end up with sbm plates like it is sounding here, I need to send you a check asap. :beer Maybe it would soften the blow Andrea has planned for you :spank: :laugh:
plate is now 3.750 wide x .950 on the big end of angle. correction; 3.500 x .950. need to get my new bifocals ou:
i dont have a sbc to compare all the differences. tell me how close. i do know i have to cut 1/2" out of the middle of the sbm. that requires a few different setups because i only have a bridgeport(wish i had a horizontal miller too). like mill the top parallel to the bottom so i can use it as a datum surface when i put the 2 halves together(epoxy them??) and cutting all the unecessary flanges and base off the intake. still have to configure the t/stat. thats an issue. i thought of piping the freeze plugs on the heads instead. any body know if that would work??? back to the sbc. do they offer any bigger port runners? the m1 is not that bad. when i get the other m1, we will see how that compares. dave, when you get yours, i think you will be somewhat impressed with it. too bad mopar doesnt make them anymore. get 'em when you see them. i been away from machining for 11 yrs. my right arm and shoulder is sore from cranking that table back and forth btw, went to a mopar show this morning and i think that intake kit that bob has is a holley intake. looked damn close. all you guys are reading this and no suggestions or comments ???? c'mon make my brain think.
Reasoning? This would be my choice to adapt and looks very much like the manifold that was used on TuBBed's 350. Victor Jr.
Your choice hear makes things much easier. A few years back I was considering this one too. Would have looked quite a bit different when I was through.
dont know what that fits, but if its small enough, relocate the 2 middle runners and you would have one for a 340 !!! what is it bill? john
The last one is a Edelbrock Victor Jr. for a sbc. Great single plane with excellant distribution. Really wakes up over 5k rpm.
John, The strange looking one in my Hmmmmmm post is a SB2 upper manifold also for sbc. NASCAR short track stuff. They use a seperate valley plate to handle the water crossovers and then bolt on the upper plenum piece. Intersting concept.
i saw a sbm vic jr and it was about 2" shorter than the m1. refer to ebay item above. bill, since i dont have any chevy stuff, have you done any comparions on the fit? head to head, frt ot back?
i listed the other m1. if you wanted to get a little different. http://cgi.ebay.com/ebaymotors/MOPA...tegoryZ36474QQihZ013QQitemZ230023791965QQrdZ1
sbm; the first m1 i listed is mopar p/n P4452893. i have that one. the one i got today is p/n P4532598AB. it fits w7,8,9 heads. you ever come across one, grab it. if you find an old mopar perf catalog, grab that too. pictures!!! that intake is about 2.5" taller than the m1. massive legs on it. fits up just like the m1. now, finish rough milling the ports to get a close idea where i stand in this mess. damn close as far as adapter plates go. still half to machine the m1 so i can work/fit to the plates. sounds easy, huh. wish i had xray vision. would make it a hellava lot easier. hopefully...hopefully it will be ready for cecil. and my back is killing me. i am out of shape standing at the machine. open for any comments, ideas or suggestions. dave, called a place in texas, nice guys, about the paxton for parts, etc. decent prices. nice winter project. john
I'm glad to see that there are some people who are serious about SBB 350's!! Keep up the great work, I've been trying to make a sheet metal intake but it hasn't worked out so far....
thanks anyway. i know this is not going to be 100% perfect match, but it will be better than the manifolds we have now. if i could only weld aluminum....
sean, try mocking up one in pvc sheet stock. easy to glue and work with. thats one of my other projects. i think it could be used if an insulator plate is used. ???
just for reference, on a 850 carb, what is the distance from outside hole to outside hole? almost screwed up the plates. i was having an issue with port alignment. then it dawned on me. i was setting the plates of the valley rail instead of the bottom of the head like where the intake gasket is based from. ou: now the plates are stable for fitting. cut the top of intake parallell to the bottom for a datum surface. cut the inside for a locating edge when i cut it half and a slot in the middle for the bandsaw. you have to watch out on how far down you cut the slot because the intake v's go to the inside. i think there may be some puttying when the mating surfaces are machine. all in all its not such a hard job doing this. wouldnt want to do a bunch of them. who's got the rob's intake now? i want some better pics of it. dave, did you know on a paxton you can make it a blower or sucker! no need for a blow-thru carb. they made an adapter one time. have to find one or a pic of it. cool!!! as always, any suggestions,ideas or comments welcomed john 860-871-0185
