Thanks! I like the whole sleeper look. Open the hood, and see a stock looking engine. Doesn't get any better than that!

That's why I love PS and FAST racing. Just nothing cooler than seeing a stock...or stock appearing muscle car blast down the track.

I want one... And this is going in a 64?

[gtofreek]

It's going in a 67 GTO.

Good choice...cuz I have one...lol

[MUSLCAH]

How would that set up work with Tri Power....that always looks good and stock

Paul, is this the out sourced dyno that you all have used before?

Did you mention sometime back that your place of employment plans to have a dyno up and running some day?

Yes, we are having them dynoed at another shop right now.

We had a dyno years ago, but it belonged to someone using our shop, so we had use of it. We now have all the dyno software, water brake, water pump, etc., to get it all running again, but we are in the process of building the dyno room, and engine stand. We can't use a static unit like a Superflow, or DTS. Ours needs to be moveable, so we can install and dyno test complete exhaust systems.

TH400 with 3.08 gears?
What torque converter?

I had Mikes Transmissions build the trans and he also had the converter built. We talked extensively about the engine and gearing. Its a 10" around 2800 stall.

The car currently has 3.55's but I am planning on swapping them out for 3.08's

Did your engine show up?

Yes. My FIL got in late last night so I haven't seen it yet. We lined up borrowing a cherry picker so tomorrow morning we will get it on the stand. I already got all my engine brackets sandblasted and painted so I am ready to dress this thing out. Cant wait!!!!!! I will post up some pictures tomorrow.

Do you know the part #s of the SB Ford rocker arms? That is a serious saving over Crower steel arms and if they work on your engine why not every Pontiac engine?

Paul posted about this in another thread when I asked about them.

The ford rockers are shorter than Pontiac. So with 'taller' than stock valves they will help with rocker geometry when trying to get roller tip centered on the valve stem. Pushrod cup is also on a different angle than Pontiac. So that requires a little more attention to work right.
Not a good idea with stock valve heights...I have seen post here on PY and a few other places where people are using them with stock length valves. I'ld have to guess roller tip to valve stem and pushrod to cup isn't optimum on those engines.

Thank you for the post. Can you define "longer valve" for this? 544127 and 9771980 SD valves are longer and are good to use (the lengths at least) I would think in roller cam applications where lift will be .550 (or some such) or greater. Perhaps the Ford 1.6 rockers are the way to go on any such application? It would be good if someone did a thread titled "when to use sb ford roller rockers". I would do it if I had the knowledge but I don't have the knowledge..

[tom s]

John,the geometry on the 61-63 SD heads are not the same as later heads.The factory 1.65 rockers for them and later 1.65s cant be interchanged.I think you might be in uncharted territory using ford rockers.Tom

[61-63]

Tom, I mentioned the heads only to state that the valves for them are longer than are normal Pontiac valves, which is the driver for using the sb ford rockers if you read the thread Quick_Silver posted a link to. For folks putting roller cams in 670s, #16s, etc. (or ANY regular Pontiac head), having higher lift and thus needing longer valves, it would be useful
to know at what valve length one could begin to take advantage of the sb ford 1.6 roller rockers. 2.11/1.92/1.77/1.66 Ferrea valves on Butler's site run 4.98" in length and slightly longer but SD valves 5.30-5.4" or so. And there are valves at 5.10+ or - in between. So what valve length enables one to start taking advantage of the shorter sb ford rockers? Crower enduro 1.6 Pontiac rockers are $590 on Butlers site and sb ford comp cams 1.6 ultra pro rockers are $340 on ebay from cnc motorsports. That's a $250 difference. Guys doing longer valves on roller cams might want to know when specifically they could take advantage of the comp cams sb ford rockers.

I'll reply to this later on.

When it comes to using Ford rockers, there are times when they work, and times when they don't.

When I say longer valves, I'm not talking longer than the short valves in 6X heads. I mean longer compared to what came in a particular head from the factory. You need to keep in mind that when Pontiac uses a non adjustable valve train, the valve tips need to be at a certain height, regardless of head used, to be able to use the same pushrod in any engine[keeping in mind that 66 and older engines, and some 67 engines used shorter pushrods than the later 68 and up engines, including some 67 engines]. The valve length from the factory was determined by the depth of the combustion chamber. The deeper the chamber, the shorter the valve. When you install a longer valve than what came in a particular head, the valve tip becomes closer to the rocker stud than it was when stock valves were used. Now if you use a Pontiac rocker arm, the rollout pattern will be farther out on the stem tip, closer to the exhaust side. By using a SB Ford rocker in these applications, you can get the rollout pattern closer to center of the valve tip, where it should be. I find that when you increase the valve length .100" or more, the SB Ford rocker becomes a viable candidate. It's not a good choice for stock length valves. The 468 this thread was created for has valves that are .185" longer than the stock 670 valves, so the Ford rocker worked out very well here. I also find they work well in 389/421 heads when a .100" longer valve is used to get the spring installed height longer.
