I am trying to do things right this time.
My 59ht with an r-I (#1984) is punched out .040 ,I put it together with erb 9.8 to 1 dished pistons and thin head gaskets ,then I added a r-2 set up from Lionel ,Mallory dist. and carb from tbo,ported the heads, and used the high output pulley combo from erb.Making about 5.5 lbs. of boost.
It ran great for about two years and then I notice a small drop in wheel spin shifting to second ,
Couldn't figure out why!
A friend suggested a leakdown test, I said fine once he explained what it was ,so we did it.
cylinder number one 98% Great
cylinder two thur eight Make the radiator erupt ,Ok bad head gaskets, pulled it apart, luckily no glazed cylinders. Now I want to make sure this doesn't happen again. So I put the engine back to-gether with thick head gaskets and low compression heads with r-3 valves.
My friend who is very knowledgeable about boosted engines ,Gave me a crash coarse in FUEL TO AIR RATIO Numbers and explained I needed A wide band oxygen sensor to check my AFR under boost .Well this we did and sure enough I was running 13.5 to 14.1 under boost which is very lean and dangerous for the engine. He told me I needed to find out what the ideal number should be or close to ideal. Phil Harris is the only one I could find so far, that had a idea .He says and my friend agrees it should be about 12.0 to12.5 approx. . great I now have a number to shoot for .
So I bought jets and metering rods from edelbrock.
I have 401 primary jets with 7547 metering rods and 389 secondary jets. I am going to try 398 for secondary jets and see what the numbers are .
Anybody else familiar with this situation.
