Are banana groove shafts necessary if I run aluminum roller rockers with needle bearings? Can c a guy use factory hydraulic shafts. Thanks. Kim

Hi guys, just wondering what you guys think of this pattern. I rolled the engine over by hand after adjusting the rockers. Any and all input appreciated. This is on a set of Speedmaster heads with Comp Ultra Pro Magnum rockers. Thanks. Kim

Somebody wanted to see what they look like. Can’t remember what thread it was. A little rusty. Kim

Do u need a mini starter with TTIs. 73 Cuda 340. Thanks. Kim

Has anyone used the stainless steel roller rockers. Thanks. Kim

I’ve seen u can get the adjusters for ball and cup pushrods. Can we get the ball and ball adjusters for our adj rockers? If so where? Any links. Speedmaster has them with their stainless rockers, but not separate. Thanks. Kim

Who has theirs installed and up and running on a near stick build? What did u use for rockers and pushrods? .506 lift with hydraulic lifters. Thanks. Kim

I’m alittle disappointed to say the least. I got this from a well know shop 20 years ago so no going back. First thing I find out is the crank is a 318 forged crank. No holes drilled in the front and rear rod journals. Got a useable 340 crank now. Pistons are new and pretty close in grams so...

So with so many members that bought Speedmaster heads what rockers are u guys/gals running. The cam has .502 lift hyd flat tappet. if u want to know more about the rest of the build check out my 340 upgrade thread. Thanks. Kim

Ok, since this build changed a lot I’ve decided to start a new thread. 1970 340. Stock crank, rods with beams ground down and shot blasted. 2332 forged 10.5 pistons. The pistons are .015 a ove deck. The will be mills down for zero deck. My buddy has decided to go with TTI headers 1.5 to 1.75...

Is there an up side to running a slightly longer valve? As in .040 longer. Is there a down side? Does rocker geometry go all to hell? Thanks. Kim

I got these 20 years ago. Been in cold storage ever since. Have a little shall I say porting. They were/are 1.88 but came with 2.02s. What do u guys think. Thanks. Kim

Do all of them have the hole drilled under the exhaust port for the smog crap. Thanks. Kim

1970 340. Pistons .040 out of the hole. Would u try run a closed chamber aluminum head or the X heads. Any and all input welcomed. This is for a street car that will never be raced. Thanks. Kim

Does anyone know/have the compression height/distance for a piston that’s flush with the top of the deck? Non milled factory height. Thanks. Kim

Does anyone have 1? Anyone have any real world data? Thanks. Kim

I have .008 with factory rods. Would a light sanding on the big end work? Or mill some off? If not what’s the best way to gain some. This is a 318 poly crank going into a 340. Thanks. Kim

In stock form would a 98 360 mag have much more performance advantage over its LA brother. Thanks. Kim

I have a 75 duster with the 360 HP engine. Will 1 of these cams pick up the low end power very much. Is ther other ones ground like the whip I will be putting on a Holley street dominator intake as well. Thanks. Kim

.....Car has factory 360, 727 and 3.21s in it now.......I can pick up a 10.5-1 408 short block for a decent price........would it be worth installing it with a mild hydraulic cam, 1.88 stock heads and stock dual exhaust in a 75 duster or should i just leave as is , would this combo run low...

.........when using the mellings hv oil pump on a stock 1970 340 i've found that the oil pan hits the pump.........i've massaged many pans before, but on this 1 i dont want to and the owner insists on using the hv pump, i've tried talking him into a stock pump , but no way this is happening...
