78' Silverado · 10-11-2003, 01:33 AM

Well....I called Comp Cams. And I was talking to one of there Tech theres. I told him all the info about the truck. And he matched up a Soild Roller cam for me. All i really remeber is the Lift and exhaust/intake which was a .342 Intake.....346 Exhaust....at a .575 lift. Anyways I got the Part Number. And wow lol. For a full cam "set" it was 1,000 Dollars. But for the Cma/Lifter set it was about 700. I was like DAM!!!!!!.....Better start savin lol. Cuz thats half of the cost of my heads haha. But....I will only get the best of the best.

BTW I got my lowering springs in oday!!! yay!!! lol..now all i need is my flip kit haha :P Later Yall!!

have you ordered your flip kit yet? if not, i've got one i'm interested in selling.

Just curious, but why are you going with a Solid Roller Cam? You can get by just as good (if not BETTER) with a Hydraulic roller, and it will be easier to maintain...NOW, if you're going to spend a LOT of time above 6500rpm, THEN I DO recommend the Solid Roller...otherwise, Hydraulic Roller will be fine.

I went with a full hydraulic roller set-up from comp cams and love it. One word of advice: If you plan on driving your truck on the street daily go with a cam that has a lower duration @50. Anything in the 300's is way to radical for a daily driver. Nice thing about CompCams is they offer the roller cams with a cast dist. drive gear so bronze gear is not necc. Good luck 342-346? WOW! I think that tech guy is doin' Oxy's wth Rush

78' Silverado · 10-11-2003, 03:05 PM

Yea...I am still guna consider that cam. But..My friends wants me to get htis cam he thinks would work better but we'll see. And yes MY flip was odered last week...it should be here tuesday.

We just put a comp cams 12-407-8 hydraulic roller cam in a buddies 76 corvette. Man that thing runs nicely!

Not sure the mileage yet, but it's got 15 inches of vacuum at idle.

Hmm, on my daily driven 87 Corvette, it's getting a Comp Cam that's 112 C/L with 219/219 duration @ .050, with .560/.560 lift @ .050

It is much cheaper to go roller if you have a one-piece rear late model block as you can use the factory stuff......the GM roller lifters are made by Crane anyway.....and the GM roller Vette cams are pretty good for a daily driver.
That is how I did my 383 except I had Crane make me a custom cam.

TwinTurbo · 10-13-2003, 03:44 PM

You don't need a later model block for OEM roller lifters. The V8 lifters are taller than the flat tappets but the 60deg. V6 uses shorter ones, they fit inside the lifter bores and you can use stock retainers, only need to profile the retainer edges and trim own the coolant walls (the radius sections), then true up the lifter bore tops if needed, drill & tap the cam bore and install the spider plate. The plate will have sufficient tension because the later block uses pedestals, the earliers don't have it but the lifter bores are about .400 lower too. Will be good to about .55 lift, above that anyone would go solid roller anyway.

Cheap roller cam for 1/2 the money of retrofit stuff and good quality too, no worries about beams getting loose and rollers digging into the lobe.

SCOTI · 10-13-2003, 06:13 PM

TwinTurbo, 4.3 vortec roller lifters correct? And could you explain the "trim down the coolant walls ( the radius sections)" in more detail. This sounds interesting.

TwinTurbo · 10-13-2003, 07:38 PM

nope, they must be the (3,1L) 60deg. V6 lifters, GM17120070

You must profile these sections: (green, of course on BOTH sides)

SCOTI · 10-13-2003, 09:45 PM

Oh....... duh, you did say 60deg. I should've read what I was reading.

DMAN · 10-28-2003, 05:04 PM

Which push rods would you use? Do the tops of the lifter bores need to be machined or could you do it with a die grinder?
