    Another 87 octane/aluminum heads question

    It's not an A body but it is a small block, and a somewhat odd combo. I have a '90 360/727 w/4.10 gears in an '86 Ramcharger 4x4. It's fed with an unmodded swapped in '89 factory TBI. The current engine combo consists of an AirGap intake, shorty headers, mildly ported 72cc 308's, can't recall...

    Timing Chain Tensioner Oiling

    The stock cam retainer plate has a relief on the back, aligns with the right bank galley, and the galley plug had a hole for lubing the chain. Replaced that with a tensioner, which has no relief on the back, and the plug the machine shop installed has no oil hole. Chain/top gear gonna run too...

    Retainers

    Been looking for retainers that'll fit '90 308 heads. Type 1990 360 into Summit's or Jeg's search engine and I get nothing. One goes to '89 and the other '86. Far as I know they're the same, but not 100% certain. Jeg's has some Comp retainers, but they seem pretty generic. Fits Ford, Chevy...

    cam spec card

    Correct me if I'm wrong, but -15 btc @ .050" does mean the damn pointer on a degree wheel should be to the right side of the TDC mark at .050" lift? Installed centerline's 111, had to advance the cam a full 8* to get there. Helped the .050" opening number, at least it's at 12* atc instead of...

    Intake Port Tumble

    These are '90 360 pickup 308 intake ports, and as you can see the mismatch is awful, about 3/16". This gasket is very close to the Air Gap's port size. If I open the port to gskt size, looks to me like that will only induce more tumble on the backside of the pinch. I'm going to pare down the...

    '90 roller block

    The LA roller architecture is supposedly the same as a Magnum, right? How much lift will the factory setup swallow before the lifter hits the guide link? Eyeballing with the stock cam on the base circle, looks like the link limits lift to around .520" with a 1.5 rocker.

    TBI torque

    Been lurking, lots of top notch engine builders here, want to ask some advice. I have a '90 roller 360, want to drop it in a 4x4 Ramcharger. {Yeah I know, bear with me, A body stuff to follow soon, I promise} It has TBI, and I'm looking to maximize mid range torque, since it's limited to...
