LOL, I never said go back to iron heads, JUST saying that they can be fun, I've made very good power with them.






ps, 4700lbs 64 gal-x-e   460ci dove heads,std bore...11.90 thru the mufflers c6,no power adder  1150 dom carb,4200 converter, 4.56 gear et streets

Ya this car went 11.70s with the iron heads and solid flat tappet. Cam. In a 1957 fairlane. With full interior . With 4.33 rear gears and c6 .

4700LBS on a 64 Gal-x-e were you towing a corvette too?

or a few spare engines?

I know them galaxys are big but i didnt know they wher 4700 lbs ! Our 57 is 3750 with driver . All factory stuff minus the glass hood and the aluminum heads . Them iron heads. Felt like they weighed about 500lbs tho lol. .

big driver, there was a write up about it the ford mags  , we weighed it on 3 different track scales, I think it was 4699lbs all tools,spare,stuff in the trunk, stock steel ploice car wheels,etc etc. now the car is up north on the street , haven't seen it in a long time

CooL...Thats hauling the Laundry!

I like the galaxys . My dads friend had a few 63s. And i put a cage in a 62 for a friend.. neat car

Head pic update

Headin home now .. u dont believe i have the heads i say i do ?

hopefully that worked

motor also has crower severe duty roller lifters and comp ultra pro magnum rockers 1.73 ratio

AND, if the pistons have not been re-notched from the Iron Head days ... 8 bent intake valves, also.

the valves aren't bent . I just had the heads gone through 2 weeks ago .  the pistons also didn't show any marking showing that there was any valve clearance issues .the pistons may have been recut but I don't remember them being done

linearfab wrote: They are the same pistons we ran with the old heads .  Im trying to find a picture with the heads off of it .  But they r old trw forged pistons. Not. JE like i first stated .  The pistons have been in the motor for probably 15 years or so purchased by my dad .   Everything else is correct tho (correct as in type and brand )

Is it possible that these pistons were fly*cut at some point to clearance a big cam and that is why the valves are not bent, because a mis match at 7200 rpm would bend the valves for sure. I would recommend finding the baseline by removing the heads, checking all the clearances, advance the cam check again, check the pushrods too, then look at the gears, stroker etc. for the winter changes.

Unless your TRW pistons have had other notches re-machined or the camshaft is installed way retarded the valves WILL make contact with those pistons using a camshaft of that size.
Of course if those TRW pistons are for a 460 and .100" down the hole at TDC then there wouldn't be any contact.

I have built HUNDREDS of these, (not embellishing), HUNDREDS and this is how it is.

You don't know what combination you actually have ... that is crystal clear.
So, you don't have to put up with me telling you anything else to try and help you ... at least until you can convey exactly what you do have.

EDIT: I tried to attach a photo showing that the notches for the two heads are 5/8" of an inch in a different place but, i must not be doing it correctly.

this^^^^^you can check clearance @10* before tdc for ex and 10* after tdc for intake with a dial indicator.

Ya it wouldnt let me attach photos . I had to. Use my photobucket and just paste the url. To get it to work

I feel like You guys Think im argueing with you About stuff . Im not at all trying to argue im just stating what i know ( and its not much ) . I no the valves dont hit the pistons. And that the Piston isnt .100 in the hole . So they must of been recut . We have had 2 solid rollers in this motor with these heads. First cam was. A comp cams.728 lift .260/.270 @.050 . And was installed by the same guy that built the motor . But it broke a lifter(#5 exhaust). And hurt the cam so we had this new cam ground and put in. Which doesnt tell you shit about the pistons other than. the clearances have been checked at least once by the builder and the heads /valves. Checked. 2 weeks ago when i had him change the valve springs and retainers for the new cam

The first cam was closer but, still to big for that vehicle combination.

The piston being .040 and made by JE is enough to tell me it's a custom piston. That being said , it could have a valve pocket for the Aluminum SCJ head "by accident" if not intentional. There "was" some confusion years ago when "SCJ" was called out for cylinder head type. And it "could" have cleared with a smaller cam and iron passenger head.

I thought he backed up and said they were the old TRW pistons............... I will read back and check.

Sorry missed the "they're TRWs not JE" post so disregard the above. I also do not know how the valves clear the pistons when using the SCJ aluminum head. The "new" valve location of the head is WAY off what the piston "should" be.

He also said his old cam was a solid Flat tappet, and then it was a Roller, I was at the track a while back and a guy was having troubles with his car so I thought I would help him out, so I ask him where his timing was? ( he pointed to his distributor and said right there) I turned and left
