anesthes, nice set up, but we need to talk about your ignition wire routing. Seriously, if you have the same problem as me, burning wires on the headers, I would recommend Design Engenering Inc. heat sheath(?). I use them on my two headered cars with no burnt wires in three years. Elsewise, I think you got it goin' on.

I've never had a problem with burned header wires on my fbody cars, but the headers on the vette run a little differently. I was gonna get some slip on boot covers to proteect them.

Joe - I'm kinda surprised you got a coil in the cap dizzy to work, too. Figured a small cap was required.....

anesthes

iTrader: (12)

A small cap or screw on coil in cap works, the clamp on style coil in cap won't clear the rear fuel lines out of the miniram (i tried). the screw on style is like literally 1/4" narrower and clears by like 1/8". heh

Some stuff on the vette is crazy tight, you should see the oil temp sender and gauge sender on the back of the block, which is also 1/8" from the dizzy and 1/8" from the wiper motor. Other things however have tons and tons of room.

Ah, I see now. I don't think the dizzy fitting or not has much to do with it being a Vette though, its all the LT1 or MiniRam style intakes and the fuel rail locations, right? I wouldn't want to try and fit a large cap with my SR either....

you ever get your superram problems worked out?

Pretty much, you can read towards the bottom of the last page here for the details (don't want to hijack this thread):

Bottom line is I've still got some differential between the two WB's, but I've got it down to .75 - 1.0 at idle and around 0.5 at cruise, a little less at WOT but it actually seems to flip-flop between the sides at WOT. So from all appearances, it is something inherent to the SuperRam. Guess I'll just tune for for which ever one appears to be the leanest to save engine damage. Especially if I ever decide to install that NEX kit I have sitting in the garage.....

Looking good guys!
I finally got my CAI to pan out (3.5" SS Pipe)
This is how it looks today so I figure I should post a pic before it gets any dirtier Been driving it for about a month of weekends now. Just looking for more power now.

Looks a lot like my 3.5" setup - except your battery is on the wrong side and you have the CAI on backwards.....

What valve covers are those?

anesthes

iTrader: (12)

Stock fbody covers for a pre 87 TPI car. I wanted to use the cast vette covers, but the rockers wouldn't clear. These clear the trickflow alum rockers.

-- Joe

83 Crossfire TA

iTrader: (2)

Really? are they steel or aluminum? I like how those look and have been looking for parimeter bolt VC's... I definitly like the cast 'vette ones but I suspected that they'd be tight, I keep hearing that they'll work with double gaskets but I haven't found a set of them anywhere either.

anesthes

iTrader: (12)

Those are stamped steel. Pretty much the same as the centerbolt ones, just parimeter. I've tried a lot of covers over the years, and the OEM baffles are just the best.

The cast vette covers have these stupid tabs cast into them that hit the rockers. I guess they could be cut off, but i wasnt in the mood to try it and then have a tap later on.

-- Joe

iTrader: (1)

I have a set of the cast Vette covers that I'm trying to get the grey off of now so I can polish them.
That stuff is tough, anyway do you think they will clear rollers if I cut them?
They are Harland 1.5's
Don't want to do a bunch of work just so someone else can use them.
Really hate the idea of double gaskets, thats just problematic.

83 Crossfire TA

iTrader: (2)

Thanks antithesis, it seems that those valve covers from that era just look right under the hoods of our 3rd gens… I just need to get my mitts on some.

JP… I know I’ve seen them used with RR’s, but I don’t know if anything was done to use them. You know that you can get double thickness gaskets instead of using 2, right?

anesthes

iTrader: (12)

antithesis?

vernw

iTrader: (2)

Hmmm... I've never heard that before. May have to check that idea out. I just ordered a new set of the LT1/LT4 composite valve covers. Trying to see if they will quiet down the sound of the roller rockers (especially the ProMag steel ones I want to be able to put back on the engine). Hoping they'll clear the SR runners a little better, too.....

Lo-tec

The 1.6 roller rockers (crane?) that come in the hot cam kit will fit the vette covers once clearanced.

vernw

iTrader: (2)

How about the Comp 1.6 steel Pro Mags? I think I've got a link somewhere that shows a bunch of grinding being required...

Lo-tec

No clue. I'm in the process of rebuilding that engine; I will try and remember to snap some pics of the valve covers this weekend.

83 Crossfire TA

iTrader: (2)

Yea, they’re the same as the crane golds.

They’ll work under the composite center bolt covers, it’s a fairly common thing to do with the LT1 4th gen guys

The pro mags are a tighter fit then most of the others… I know that they don’t won’t work with the stock breather baffles and the inner valve cover supports without a bunch of cutting

Lo-tec

Here are some pics of the stock valve covers from a 92 vette LT1 engine after modification (and a few cold ones)!!

83 Crossfire TA

iTrader: (2)

Heh, how many cold ones?


Tim, you working on Doug's car or is that something else?

Lo-tec

all of them

and yes, the LT1 hot cam special has found a new home in dougs 95 caprice, along with a yank 3600 converter and long tubes.

ws6transam

You got that right. I am using stock L98 valve covers over 1.6 steel Pro-magnum roller rockers. I had to cut out a leg from each of the supports, then dimple out a portion of each of the ribs in the top for clearance. They look somewhat "odd" from the outside but they are nice and light and dont leak.

...as for the comment on the Pro-Magnums being loud: They are loud. In fact you can hear them ticking away so much that you would swear that there are a bunch of bad lifters in there! I've checked them a bunch of times, and the engine runs great & all, but I still feel weird whenever I sit in traffic and listen to all that clicking out front...

vernw

iTrader: (2)

That's what I'm hoping the composite covers will help eliminate by "absorbing" some of that rattle. I'm also concerned about what the knock sensore will do with all that extra noise - nothing I hope!

@ZZKKER

iTrader: (1)

my comp pro magnum 1.6 rockers are quiet as can be. were yours loud from the get go or did they develop the ticking as the miles are driven? i only have about 30 - 40 min. of run time on mine so far.
what is your oil pressure at idle? mine is around 40 psi after it warms up (hv moroso pump), maybe that is why mine don't make noise.
regardless, if mine develop the ticking later on, i will just need to remove the mufflers so i wouldn't be able to hear it any more

thanks

It has more to due with the cam profile than the pro-mags. If have had them on three different cams, first two were very noisey but the cam I have now, they are very quiet.

im on a comp cs xr276hr 12 grind. the part number is 08-503-8. sound real healthy
i am also running tall cast aluminum valve covers.

What were the differences in the cam profile that caused the PM's to be noisy? Just curious....

This is an olde pic of my 383 cid mini rammed motor. I'm running Edelbrock ported RPM heads, ZZ-X cam. I have since cleaned up all the hoses and plug wires. Added a new set of Jet-Hot coated Hedman Hedders. New valve covers too...I'm in the process of installing my ATI Procharger with a 3 core intercooler. After I'm done wit that I'll post a new pic.

What valve covers are those? I need something cheap for my truck and those look like they would fit in allright, almost look like a nicer version of the early 80’s stockers…

TransAm12sec

They are known as black crinkle valve covers.

I'm sure summit/jegs has them.

Here's another place. These are the tall versions, while you can get the short versions.
