Gentlemen,

Thank you for your input.

From your comments I gather the following:

I first need to strip the head from the engine. With this done I need to measure the deck clearance to the top of the piston and the cylinder bore diameter. As I am going for a fairly mild build I don’t expect to have to use anything other than the stock Felpro head gasket. With this information I should then determine the head volume and buy accordingly. If I choose to LPG pistons can I buy them as .030 over or do I need to go to a .060 overbore? The engine has been rebuilt at least once so I presume it has been bored already.
I am still undecided about zero decking. It sounds like it is not such a good idea on a 292. As I am only going for 9:1 CR and sticking to a fairly mild cam I would not expect to run into detonation problems.
A lump port head is a good thing. If I’m spending that kind of money I should go for the 1.84 I and 1.6 E valves. With these valve sizes and one of cams described above is it necessary to use bigger valve springs? In this day and age of unleaded fuel should I just get hardened valve seats installed now? Bear in mind this will be a supplied head and not a rebuild of my current one so I wouldn’t expect valve recession.
Thanks for the CAM info. I was hunting on line yesterday and couldn’t find much for 292s other than Clifford. Larry, where are the cams you describe for sale?
Exhaust. Efi-diy, I take it you mean 2” downpipes? Unfortunately this truck has a serious box frame chassis that doesn’t lend itself to routing a full dual system. I don’t want to lose ground clearance. What would be the preferred set up for a single outlet system?
Efi-diy, do you sell fully assembled Megasquirt boxes for the inline 6? I’ve started attempting to digest the info on their website but that is a lot to get your head around. I have no problem with harnesses but I tend to come from the ‘If you can’t fix it with a hammer it must be an electrical problem’ end of the spectrum so building boards myself is out. I looked at the Affordable Fuel Injection kit but I think I prefer the idea of being able to tune it myself.


Thanks for the input. I bought Leo’s book and read it and found lots of useful information. My only problem is that it fells like it is geared to the rodder or drag engine builder while I am looking at a warmed up truck engine. I’m trying to refine that information for my needs.



Hopefully I’ve included a picture of another truck showing the final product I am shooting for in my build.







Of course, mine looks like this right now. A long way off and a lot of time and money to spend!







Thanks
