Re: 4 Questions - Isky Tool Room Springs VS Chrome Silicon & Titanium Retainers On Street Engine

Will do, Bob. These are somewhat different than beehives, I take it? Would PAC be the best choice there?

Thanks,

Harry

4 Questions - Isky Tool Room Springs VS Chrome Silicon & Titanium Retainers On Street Engine

Application : Street engine with occasional track use limited to tuning. Will not exceed 5,500 RPMs. Chevy 292 inline 6 using same valve train components as small block Chevy V-8 except for 1.72:1 big block rockers and 7/16" ARP rocker studs. Mild solid lifter cam grind with 0.495" valve lift. Rock...

Re: Rhoades Lifters

Aha! A clue!

Re: Would you ever use Rhoades lifters on a solid lifter cam?

Jack, as you know I will be running the Rhoads V-Max lifters on a solid lifter cam in my 292 Chevy inline 6. Will let you know how it works out. This will be an experiment. The object is not to crutch an overcammed engine on the street nor to boost manifold vacuum at idle for a circle track engine r...

Re: Ir intake manifolds and carbs

Worked on the problem of building an IR setup for the 427 stroker small block some years back. As you say, finding Weber carbs large enough to do the job is the issue. I did it this way...... Calculated baseline and figured I needed at least 46 - 47mm chokes (main venturii) and 58mm throttle bores t...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

:D Its not such a hard swap, Paul. The later model inline 6 uses same bellhousing as small block and big block V-8. So I will use a '55 - '57 Chevy V-8 passenger car bellhousing, 168 tooth V-8 flywheel and 3-bolt starter that bolts to the bellhousing. This will allow me to retain the stock '57 bellh...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

Harry, wow, first off; very kind of you to offer! With that said, I haven't rebuilt a carburetor since my teens! Autoshop or the Texaco; can't remember. I wouldn't mind trying again though; be a fun project x2! I can PM you my info if you'd like. I believe Coker still sells bias ply tires, maybe wo...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

Yeah, grenading a flywheel is no fun at all, Paul. Not a thing I care to repeat. Regarding shifting for others...... When we were in Jr. High (we were 12 yrs. old), we used to, errr...... 'Borrow' a friend's Step-dad's work car when he would leave it at home and ride to work with a buddy. It was a '...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

I will be looking into how the pulley behind damper mod would work with my setup, chevyfreak. Pretty sure at this point that I will be running the large 8" malleable iron dampner I have here. Bought it in the early '80s from a Chevy dealer for an engine I was building, but never used it. The engine ...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

:D My engine bay is even tighter than your '59 Apache was, moregrip. I am swapping the 292 into a '57 Chevy passenger car. This will be a road car. A driver. And I will pull a boat trailer with it up in the Texas hill country from time to time. I will use it like a truck. That's why I'm building the...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

......Question, if you had the room, would you be going the DCOE route? That would be the most logical choice, given available manifolds...... Or Dellorto DLHAs. I like doing things differently, though. So I would look into sliding valve carburretors...... SU, Mikuni HSR. Something along those line...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

Good luck with your build, moregrip! If both Larry at T6 Racing and Mike at Sissells believe the 194 combustion chamber can be unshrouded for bigger valves and will work best for you, they should know. Regarding off the shelf cams for these engines other than sourcing them directly from cam grinders...

:D Should be fun! I will follow with interest. Please keep us informed as to your progress. Regarding the 194 head...... If you don't have it as yet...... Yes, the small chamber head will raise compression some, but the open (bathtub) chamber heads breathe better and shroud the valves to a lesser de...

Re: Questions Regarding Siamesed Intake Ports (9 Port Head)

I love tinkering with Webers. Especially the DCNF series. The siamesed intake port arrangement on these engines precludes modifying them for an IR intake configuration, though. So I decided to build and test 2 intakes. One will be the 3-carb intake having 3 small plenums, each feeding a separate pai...
