Looks nice

Yes, if the .050 is indeed 262, that is way to much cam. That cam could get you 8k rpm, if the heads are big enough. You should be able to get 375 hp with a 232 cam.
The 289HP heads don't have any flow advantage, unported, they just have spring seats and screw in studs. Porting isn't easy on them either. Stock they flow about 165 and the best porters can't get above 240 cfm. I had a set of C6 heads and after quite a while porting on the intake, schooled by a pro, I was only able to get 196 cfm with a 1.90 valve, good for close to 400 hp.
A EMC competitor, got 2nd place, in the last EMC with 294 ci, 235 cfm heads, dual plane intake and a 242@.050 roller cam for 440 hp @ 7.2k.
Blykins just curious, you that have built a few sbf what hp
do you guess i had in that. 030 over flatops ,10.5 CR
Ported milled 66 289HP heads with 1.90 1.6 valves. 308 deg/ 510 lift cam
think it vas 262 at .050 lift edelbrock performer rpm 650 dp holley
Hooker super comp headers, good machine jobs. 375??
That's a whole lot of cam for the displacement, head, and intake, I would think 375 would be on the high side.
Same - use the Tractor Supply PSC 1000 in a large HF tank, no issues in many years. With any tank, make sure you set up some easy way to drain the tank. I converted to a larger gate valve vs just a plug in the bottom. Lazy like that.
But is it safe for a pump that calls for water base solvent? This is Petroleum Distillate. Not sure if it is compatible with my pump?
Thanks,
I'm sure we have all experienced this in some fashion.
Working on mechanical objects exposes us to some irritating things....of which we find out in curious manners.
While the attention getting sensations you describe do make a lasting impression, I find it is the stealthy things that seem to get me the most.
Things like trac-lok additive............a seemingly benign little bottle of special lubricant.
However, should you get this on....well....anything, that thing will stink like the horrible additive for the next ten years and there is basically no way to clean it off.
Yeah, I recall the old Lisle tool, just didn't look like there was much access to some of the lifters.If you use exhaust gaskets throw them away and use hightemp silicone. I had not had an exhaust leak since late 80s when i started doing that
I have adjusted the rockers and made some jam nuts for a couple that were clearly losing their interference fit, so I think I've addressed most, if not all those issues. I did find some exhaust manifold bolts a little loose, hoping that may be part of the issue, but its not a nice day here, so I won't be running it to find out just yet. These GT exhaust manifolds have some bolts that are a bit challenging to get to, especially the passenger side rear. This is a Galaxie, I'm sure I'd get a lot of practice cussing if I had it in a shock tower car. An FE in a Cougar or Fairlane has got to be tight.
I have the factory adjustable rockers.
Making adjustments or taking measurements while it is running isn't really in the cards, as I don't have an old valve cover to cut up and don't want the mess associated with doing it without a valve cover. I don't know how messy it could get, as the pushrods don't oil and it is restricted, but it's probably still messy.
I looked at Johnson's website and it looks like they only make roller lifters now. I suppose there may be some old stock flat tappet lifters sitting on a shelf somewhere
Cafe not my style but it is nice.Thats the style the tuff guys drove when i was a kid
