that sounds reasonable.

Also, I am contemplating using 1.52 rockers on the intake side with 1.6's on the exhaust side, anyone have any experiences with this?

My buddy ol'Rj does this, he tried the 1.52's on the intake and then the exhaust and his track results showed that using them in the intake probably allowed for better scavenging using the 1.6's on the EXH.

Had a long talk with Bullet Cams yesterday, flat out great people! They will take the time to talk with you if you need.

Regarding the split ration rockers, they said yes, when using the AFR heads, the EXH ratio inefficiency is very good, so slowing down the rocker with the 1.5 will actually boost the TQ in stead of using a 1.6's on the EXH. This was exactly my thought, on accident of course, but I knew the AFR EXH flow efficiency we @ 85% based on my flow charts, so there was no need to leave it open as long, and by using a .612" lift on the Intake, this helps the top end but sacrifices some low end TQ. Since I have 210cc heads, I did not want to kill anymore of my HP than necessary.

This does not affect the timing events, only the speed of the open and close of the valve and the lift. So, I'll be using 1.52-Exh & 1.6-Intake on the new cam

Cam specs are;
228/234 @ .050
284/289 @ .006
114 CL
.3825 lobe x 1.60 = .612"
.3825 lobe x 1.52 = .581"
Overlap at .050 = 3*
Overlap at .006 = 58.50*

So of the stuff came below and the cam will be ground this week and be back in my grimy hands next week.

I put those same rocker covers on my 84. Nice for the $$$, with one gripe... I wish they didn't cut the breather holes at the factory... I prefer to have both breathers at the front of the engine.

The cam lobes they are sending you sound good. Short advertised duration with a lot of lift. That's good for matching up driveability and power. I personally don't think you need the lobe centers spread out that far (114) but all it will do is make the power curve more gradual and hold on longer at the expense of some low/midrange. I'd expect it to drive very good on the street.

Thanks Will, I'm pumped about getting it back on the road, I only drive it @ 2 months last year, it spent 3 months at paint, and 3 months at tune.

I was able to do 3 legs of the Hot Rod Power Tour before the paint and tune, so this year it should be all driving on road time with my son, he turns 15 so I get to teach him more about quality 60's & 70's rock & roll music :-)

lotsa work just to get to that point.

Almost makes taking the engine out easy.

Used Lucas oil assy lube; it seemed fine. It was green and it smelled like mint. Did they really need to make it smell like mint?
