Now that's an idea! Like the time I ordered a Probe shaft rocker setup and after running it a few days noticed a few black metal chips in the head area while checking things out. Seems the cupped pushrod adjuster screws had too deep a radius cut and the sides hitting the pushrod and chipping out.
Got the correct ones from another company. This was on my other 351W build.
Later after a year of use I found that the shafts were wearing and galling from the needle bearings. Found out the shafts were not properly heat treated and were replaced along with better bearings installed in the rockers and best of all at no cost from the new owner of the Probe roller rocker business!

Why not try one of the TFS hydraulic roller cams??

No you are right, we do need tow trucks :)

427Dart,
Did you get those rocker parts from LGM? I bought a set of shafts from him and they are very nice. Good service too. I had an adjuster screw cup that the oil hole wasn't drilled all the way through, looked like a drill broke in the hole on that piece. One 5 min phone call and a new one arrived free of charge.

Yes the Parker intake will be used with a spacer/adaptor. Cam will be hydraulic roller because that is what 95% of street guys want.

Read the 128# post and then look up the TFS cam specs. Which cam do you think will work in a 427 with a 10.5/1 CR and a 2.08 inch intake valve?

TFS have some good profile cams but I don't see any for the engine spec I am building.

LCA 128# - 104.6º LCA?

Yes! Great service too! It's been several years and I just did a rocker shaft check the other day and the shaft on No 1 cylinder looks good.

Most likely not as a technical cam pick as some of you cam specialist but I went with the Lunati Voodoo (old number 61013 because it was one of the few to give the .600 valve lift on intake and exhaust and the duration I was looking for which is 242/249. It would probably be better with a 108-110 LCA but the 112 it's on gives me a better idle and good vacuum for the power brakes.
My cranking compression with this grind is 185-190 psi.

Please my usual 2 cents..

When did Howards end up with Harold's grinds if they did. And how did they? I really miss UDHarld is why I ask.

Another point, somebody mentioned the old "Torque-Link" intake, how can it be modified to compare/perform like a good dual plane like the old 300-36 and RPM? I ask because I like it's longer runners IF it can be made to operate over a much broader rpm range.

Howard's bought ALL the designs, programs and everything else that "Custom Camshaft Company" had, when Harold started to get sick.

My point exactly. Time for TFS to add some cam options that work.

A Victor Jr and RPM Air Gap are going to need work to keep up with the ports on the TW 205 11r heads. I'm much more interested in seeing what it'll do with the PFW and adapters since I currently run one. I'm also very interested in seeing what David did to modify the PFW.

I know what a stock Chinese PFW that I mildly cleaned up did on my street/strip pump gas 297 (.060 over 289) on the dyno compared to a Vic Jr. Vic Jr is collecting dust on the shelf now. The PFW ports seem huge and flow a bunch more air on the bench, but there is a ton of taper in them and the runners are significantly longer than the Vic Jr.

Around .700" lift on the cam will fly in the face of a lot of those who buy into the idea that peak cam lift need only be as much as the peak cfm air flow lift of the cylinder head on the bench. Over that will cost you. The sharp turn of the stock intake port location combined with an 11 degree valve angle should have the heads signing off around .600" lift on the bench and looking fairly ugly after that. I never really bought into that and will be interested to see what you come up with.

Why not just go the typical route with Mike Jones? Fill out his build sheet and let him take care of it?

I'd like to see it turn more than the typical "but it's a street car" 6,000 rpm. A decent valve train and hydraulic cam should be good to 7,000 rpm without much fuss.

Should be a very interesting build.

I have a turbo diesel truck for low end torque. I personally believe anything that will be raced should be built to turn the most rpm the budget, a person's tolerance, and parts will allow. Gear for the rpm extra rpm and watch the torque at the tire (what accelerates the vehicle) go up at every rpm point. Then blow the doors off a similar budget build built for low end power car and see if the owner is still preaching low end torque at the flywheel.

Thanks Walter,

I didn't know Howards bought everything.


Anybody want to comment about the old Torque-Link intake?
