Ford Aluminum SCJ Heads/High Compression? Empty Ford Aluminum SCJ Heads/High Compression?

Post  511Fox February 22nd 2010, 1:13 pm

Are the Ford SCJ Aluminum heads relics when compared to all the other new BBF heads Question

Is 10.8-12.5:1 CR to much for the street if used with E-85 Question

Are Tunnel Rams like the Weiand Hi Ram a relic or just good for Max Effort Race but aweful on the street scratch Question

Thanks guys I love what you guys are doing. cheers Shocked

The Ford SCJ heads Work Fine.

12:1 is fine with E85 as ling as the fuel is consistant.

Old Wieand Tunnel Rams work fine, But are Ugly..... Laughing A Modern Victor Style Manifold and Dominator is a much simpler set-up to tune. But the old TR's can be made to run just fine on the street.

I hate to say it but 12.5 is not high compression, I am working to get mine up to 14.5 from 13.3....

The tunnelrams have the WOW factor for the streets but a victor engine will most likely Kick your Butt in short order..... and be more responsive and easier to tune.....

X2 on the Intake and carb setup.

12.5 with a good tune i would imagine could run on E85.

I wouldn't say the Single 4 will woop on the old TR, You might be supprised how good the 40 year old stuff can work in the right application.

After doing one on the Boss 9 and one on the P-51 headed 466 for 2009 EMC, I can tell you they do work. They are just a PITA. There is alot to be said for equal runner length and tunabilty.......

That also is VERY true. Someone should do an all out max effort tune and compare the two back to back! Very Happy

just a thought.

Are you going to try a single plane with one carborator as well?

AND, I just hate it when someone suggests an expensive, time consuming test be done by someone else so they can simply be given the results and get all the benefits of the testing told to them for free without lifting a finger, (or wallet), of their own..
Why do a lot of people even suggest that THEY are ENTITLED to other people's test results...?
Do you now get the drift of what was being said with those posts ...? LOL.

I remember a time of the past when a "carb spacer" was tested at the expense of another and another's engine. The so-called test was to prove the "carb spacer" and it's benefits. After several WOT dyno pulls and the carb's benefit to the engine has changed due to the "carb spacer" and needed tuning along the way, the engine's owner said to me, that's enough of this sh!t! If I remember correctly responding, "yea, their going to sling a rod out of your engine then run out the door!"

Just a trip down memory lane.

Dave ... your memory of that incident is much better than mine, lol.
That was just another "freebe" to add to the list of many ... I can't even remember 'em all.

I have not done the comparison, let alone a max effort deal, but hope to do a little testing one of these days. Like already mentioned by Randy and Dave... these people everyone refers to as "They", have... but likely haven't bothered with a pair of 750s... hardly max effort, even in my book.

The 4150's are a waste of time IMO. With 4150's on a TR, you might as well run the Victor and a Domie...... Now a pair of Dominators on the old TR, now thats a different story...... If you saw the results, you'd have the same look on your face that Charlie did seeing the dyno sheets..... Lets just say it put alot of old theories out to pasture........Laughing

Just get the street drivability part worked out and then ...

On my 351 that was in the car we tried that after screwing with the aircleaner and removing the ram air system with the scoopes closed we ran it up to about 115 and took it about 12 seconds to get there.
opened them and got to 120+ (thats max on the speedo)in the same time span.

I wouldnt imagine any gain on the dyno because the car is not moving.

as for the hood bit I hope to one day shed that stupid steel NASA hood and get a fiberglass version. Shocked

I have the dominator top as well, I just need to start somewhere and go from there. I got a pic of my hood that has been trimed to let the TR and a street scoop go through. I'd be happy to share if I can send a pic and someone post it up for me.
