Ok now another problem.This is a 66 425. Pulled my spare engine apart and found 1 lobe almost worn round. Hardly opens the valve. What is the camshaft of choice for a little better performance at the lower end of the scale. Idle to 3500 RPM. Who makes them? What's the story about lifters? o No:
Hank check out TA Performance, Carmen , Tom Telesco they are all listed under Da Nailhead Parts sources. Lifters can still be had from NAPA I think, or you can go with some trick Schubeck ones $$$$$
Those engines were already optimized for low RPM so if you want your power to be concentrated 3500 and under, you will want to use a stock cam or an RV grind. Here is a link to the Nailhead camshafts that TA offers: http://www.taperformance.com/nailhead_&_v6_cams.htm Though the RV12 grind is not shown on the chart we can have it made, it would be similar to the 112 listing with the exception of the intake duration, it will be 205 on the RV12. These cams are ground on new blanks, not used originals. Lifters are readily available, as well as other valve train parts such as the springs, if needed. Dave
Thanks for the Info What about the rocker arm tips? Are they replaceable, looks like they are in the manual I have. Some are worn to the point of grooves in them
Exhaust Dave I visit the T/A site a lot and would like to get the 2.5 inch exhaust system for my 66 Riv. Thinking of getting the shorty headers also. I know I'll have to either modify or have the front pipes made because of the nailhead. But the rest of the exhaust is the same as 67 Riv with a 430.
Re: Exhaust DAVE, you and I have the same problem. I need a '66 exhaust too. See my post from today in 'the bench', 'dishonest advertising chaps my rear'. Maybe if we gang up on T/A they will listen!:spank: Seems like they always leave out the '66, whether it's an exhaust pipe or an ignition switch. :beer
how streetable is the ta30 cam? its going in a .060 over 401 with 10:5.1 compression and pocket ported heads with bigger valves would the ta30 be ok to drive on the streets? oh and im runnig the dual quad offy manifold and 600's please answer i really wanna know
There's some clown running around here with a Porsche something with a huge spoiler on the back. His plate says "GOT Tork"- that plate belongs on a Buick. I hate that guy.:spank:
man what are they thinking come on a plate that says got tork on a porshe what next huh kinda makes me think of that one movie comming out called torque i swear that word is getting used for the most anemic things , a bike movie called torque what next? they shoulda called it redline thatd fit better those lil screamers rev to 10-12 grand
T/A Camshaft Dave Ordered the RV-12 camshaftfor my 66 Riv 425. Sounds like what I'm looking for. Let's hope for the best.:beer Hank
