Sidewinder...... Your crew chief is "Cool" and smartypants (that's good thing here). You must trust him alot to go back to fh. I'm guessing your crew chief is part teacher to you? His lesson is if you can make a fh run fast, you can then make anything go fast. Basics provide good foundation.
Another story for you. After two years running, I thought I would upgrade the intake valves from stock heavy 1.50" with the split guides and go to newer modern 1.72" ss valves. Yep, slowed me down again 1/10 to 2/10 this time. Figuring out why was fun. Share with your crew chief, he'll know why it went slower : ) DF
Sidewinder:
DF, The crewcheif is really a teacher, full time:) No kidding;) And abit older than me, so I tend ti listen to him:)
When it comes to the tires, first edition was with early aluminum Anerican Racing 5-spoke with a set of Hurst recaps,
really, really heavy stuff. Since I also have focus on stands, like it to periode accurate, I put on the AR 5-spoke magnesium rims with a pair of M&H real slicks. They are way lighter than the old ones, and looks cool too:)?
I have tried to hide all the modern stuff, like the rev limiter and magneto signal converter. Last year i bought a NOS
sun blue-line tach to match Sun blu-line oil and water temp guages:)
Oh. When it comes to the valves, I chose 1.6" intake and 1.58" exhaust. According to the Bonneville guys, they run with really big valves!? I have not max ported my block because I wanted to keep moore material in it as we run with more than 20 psi of pressure;)!

Sidewinder - the more hp/torque you have, the less the tire/wheel weight maybe a factor. For our situation, it's a big deal. 20 psi..... probably good thing you haven't relieved the transfer area too much. I will have to take a picture of a block that had much relieving done to transfer area and post for you. Plenty of cracks there, not from boost, that motor ran with high percent of fuel (ran it even with the cracks). DF
p.s. Crew chief is a teacher, very nice. My sister was "exceptional" elementary school teacher.
Sidewinder:
DF, you should have seen the colour on the tranfer area surface after running it way too lean;)
Lets say that it matches the coulour on the body;) But no cracks, I think the french is abit better in the casting:)
Good to know that my son is a NDT controller;)

Were all 8 cylinders showing lean...... or did it vary per cylinder? Air flow in fh are finicky. Lucky you, no cracks with that extra heat. French fh does have it good points. Optimum to start with as new a block as possible. Here's picture of serious relief in transfer area, probably around 0.125 or little
bit more. Picture not too clear, but focus on intake side and look for dark line going to head bolt hole.
