From what I member, the only down side was they only fit one way, so the right head lookin at the motor, would have the came gear/pully on the wrong end [back end by firewall]. Wich would need a custom part to fix. But probably want to get customs cams made for it anyways.
Here.... http://repcobrabham.com/ They fit the Buick\Olds 215 block so... by extension... can fit the 350... Greg
Might be a good idea to continue that topic here; was this the thread? http://www.v8buick.com/showthread.php?t=86811 Devon
Looking at the P76/Rover cam in the 350 block, all the lobes seem to line up well except for cylinders 6 and 7, where the lobes are still under the lifter bores but displaced towards the rear. The 350's camshaft lobes all line up OK. The P76/Rover cam also seems to be about .125" longer between the flange that rests against the front of the block and the back of the rear cam journal, which might mean the cam is going in too far. I will try to get another cam to try and some lifters to check for interference.
To those of you that have the parts on hand. Thanks. It looks like we could use the same intake and heads for the 340 and 350. A custom cam would be necessary for one of the engines. I hope TA takes a good look at this. If they make the older port setup their market could include the 350 - 340 and potentially 300/215 with the existing intakes. I am sure the Rover boys would like off the shelf heads that flow 250/180 out of the box. The Rover performance guys would be glad to buy those heads. This would be a much bigger market than 455 products.
A custom cam would be necessary for one of the engines. a 350 block would use adapter bearings for a 340 / Rover cam while an earlier block could have the cam journals line bored by a machine shop to fit a 350 cam. i think i'd rather do one of those and then be able to use regular Buick cam blanks whichever way i decided to go.
was this the thread? those 4 cyl Lotus heads look like the bore spacing is right but just about nothing else appears to be.
So then, we've come to the conclusions that 5-3/4 million engines were made which could use this new head, a fair number of which were of fairly recent manufacture, and a fair percentage of which were used in performance applications. Is someone going to get this information to Mike now? I know we'd all like to know what he thinks about it. I'll probably be calling him shortly after the British V8 meet (13th to the 18th of this month) but I expect Sean or someone might want to make that call sooner. Jim
5-3/4 million engines were made where is this number from? you're adding 350 production to my thumbnail tally of 1st gen style production? <3 million SBB 350 sounds extremely low for a 13 year GM production run.
Hey Bob, I'm just using the numbers we've posted so far. If they're wrong we should correct therm. 2.9M for 350 production was the number given. Seemed low to me too but I thought it came from a somewhat reliable source and since I didn't have any other number that's what I used. It appears to me at this point that we have enough evidence to conclude that the early head will bolt up to the 350, so those numbers should be included. Jim
Anyone have a relationship with the guys at TA? It would work better if the conversation started with a known person than a nobody.
2.9M for 350 production was the number given. Seemed low to me too but I thought it came from a somewhat reliable source and since I didn't have any other number that's what I used. cool. i was just trying to nail down where those numbers were coming from. it makes the "Rover style" head look very interesting from a parts production standpoint that they make up that much of the existing SBB population. It would work better if the conversation started with a known person than a nobody. true, but it's also good to get the basic facts and figures down before you go to them. they have to turn a profit, we need to provide them with a workable business plan.
Maybe T/A could get some idea of demand from across the pond by talking to some of the bigger Rover vendors in Oz and the UK. The bigger guys may even help with some funding in exchange for exclusive distributorship in those countries. o No: Brian
Someone pointed these out to me a while back and I've been kinda keeping an eye on them... http://www.zzperformance.com/grand_prix/whatsnew1.php?id=32 Just a dream I guess.... Greg
OK, here's a 350 head gasket sitting on a 340 block and on a 300 aluminum head. Jim Also from the "Pistons" thread: More info on the 350 cam journal sizes would help. Here are the 340 cam journal sizes measurements taken from the cam itself. 1.787" 1.757" 1.727" 1.697" 1.667" Front to back. Stepped down in .030" increments. Lobe spacing is symetrical from the center bearing. Measuring from the side of the center bearing to the side of the cam lobe, inside to inside: .345-.350" 1.115-1.140" 1.870-1.890" 2.670-2.680" (some casting variation) and the same pattern repeats outboard of the next pair of journals. Now I just *know* one of you guys has a 350 bump stick laying around collecting dust. How about a comparison? JB
Jim don't know if you've been paying attention to TA's 350 thread but they have said they're going to be producing a Rover style head before they do the 350 heads and intake.... http://www.v8buick.com/showthread.php?p=1238308#post1238308 they're halfway to our position already. :TU: unfortunately, it looks to me like they have no plans to go all the way.
