Don Terrill’s Speed-Talk

I went to order a Rear main seal today, but before hand I had a brief conversation with my machinist about it. I was going to use the FelPro 2904, thats usually what I use. But the machinist said to get the Fel Pro 2918 seal, which is a harder compound. He said If I was going to use the 2904 I might...

Got ya. I wasnt even thinking about it right. It will see 200 miles (AT most) a week on street and then AT LEAST every other weekend at the track( If Weather Permits).. Eventually wanna try out the power tour. I was just concerned about this motor being in a 4000# truck with a heavy 4L80 transmissio...

Thanks Joe. Seems that my only option is a dual plane if I was trying to gain more TQ down low in the RPM. I have a Vic JR 454-R. I was going to save that for a EFI conversion later. But should I go ahead with it now? Dont waste my time with the Dual Plane C454 or Air-GAp?? My setup is a 496, 11.1 C...

Yes the 4500.. Its runners looks much larger then any other "factory" intake I have seen. I didnt get to look at the C454 to long, it also lookd like the runner walls might be thinner vs a newer intake. I was looking for a good flowing dual plane, something I can improve with porting if ne...

So whats todays equivalent of the Edelbrock C454 Intake? The Performer doesnt look like it flows enough to live up to the hype I have read about the C454. The Performer only flows 280 CFM out of the Box, I have no clue what the or Air-Gap RPM flows but its casting doesnt resemble the C454.. The Perf...

496 Build. 11.5:1 CR. Aluminum heads. I am using this solid FT cam with 1.8 RR'S Advertised Duration: 287/295 Duration @ .050": 252/260 Valve Lift w/1.70 Rockers: .618/.640 Lobe Separation Angle: 108 Intake Centerline: 104 This cam needs springs in Neighborhood of 135closed - 380 nose.. I have ...

Anyone know how many thousandths per cc for the Procomp BBC 320cc heads. They are supposed to be 115cc already. After I checked these heads they are 114.3cc .. Looking to get them down to 100cc-105cc.. Dont want to mill them twice.. I called ProComp and two other people who supposedly rework these h...

It was 20 concrete steps down. I guess it was cast..

Heads are looking like they will be around 106cc, so I can go up on gasket thickness to get my compression back around 11.1:1

So I have been hunting cam and springs. I felt a solid flat tappet was gonna serve me best with the street driving. I wasnt really looking for high end HP but rather good TQ down lower in RPM.. i found a Howards Solid Ft cam I like and seems it would be a good fit for my 1.8 rockers. Howards, Mechan...

I am building a 496. Was going to go in a 84 Z28 1/4 mile car. But we decided to build a RR car with a SBC outof the camaro.. So this motor is going in my truck. It isnt going to be a daily driver.. Will be a street/strip toy. Mostly strip with some weekend cruising.. Long story short, my cam got dr...
