Group 7, that's my car. Originally a non-spoiler car, spoiler was added after delivery. NOR car, 01B. That is my favorite pic though

Richard,

Did you ever sort the 1157 Amber LED's for the front turn signals? I purchased LED's from an online site (Not Phillips or Sylvania) and cannot get them to seat either. Just curious if you found a fix.

Thanks, Nick

Mild Modifications / Borgeson Street & Performance Series Quick Ratio Box

« on: August 18, 2018, 08:48:04 PM »

Borgeson released a new PS box for our first gens in April 2018. Its a 12.7:1 ratio box that is a direct, bolt in replacement for the Saginaw boxes.

I had contemplated doing the IROC swap, as many have done. But it seemed like a lot of work chasing down small parts and getting the correct box. Instead, I took a chance on the new Borgeson box. It has made the Z much more enjoyable to drive. The feel is firm, the car doesn't wander as it did with the old PS unit. I feel more confident taking cloverleafs at speed.

It was an easy installation (did it when I had the engine out). Total cost was $600. $500 for the box and then $100 for the new rag joint. I reused the old PS Pump and lines, just had to flush it.

I have headers and this box clears them, as did the old Saginaw unit.

I've got about 200 miles on the new box. This is a must have if you drive your cars regularly. Thanks Borgeson!

Thought I'd share an update to the crate engine LT-1. Today was dyno day and she produced 369hp (6k) and 368 torque (4300) in stock trim (sans exhaust manifolds). Pretty close to the factory ratings.

Sprung a few oil leaks, but was glad to see this one come alive.

I mocked up the alternator, fan pulley, and installed the belt. Alignment looks great.

Can someone point me in the direction on how to remove the valve cover emblems?

you can tell I'm an amateur. Now that you mention the timing gear, that's probably the 0.5" difference I'm getting. Thanks.

The dampener was bottoming out, either on the first main journal or the getting hung up on one of the keys. For some reason I though the balancer went all the way on, nearly being flush with the timing chain cover. I'm about 3/8" off the timing cover now. Its on as far as she'll go.

Next I'm going to install the water pump and pulley's to see how that lines up.

I'll measure the 350 and 302 cranks and see how they stack up.

After sleeping on it, I've accepted the 302 and 350 cranks have different size snouts. Like many of the interchangeable parts on these SBC's, I figured the snouts would be the same size. Sorry for the rant above.

Hi, sorry to bring this thread back up, but I've exhausted all search combinations and cannot find an answer. For some reason, the front end of the NOS engine crank is exactly 0.5" shorter than two 1178's I measured. Which is why I'm having trouble putting the balancer on...

Does anyone have insight on this? Would I be better asking the Nasty Z28 community?

So frustrating!!!

It's called Austin's Cleaning Vinegar. When I bought it, it didn't list the acidity level, I just assumed it was higher than the 5% that's in white vinegar. Also, the label warned against drinking it.

Here's the website: http://austinsbleach.com/product/cleaning-vinegar/

I'm not a scientist nor do I play one on TV, but the Safety Data Sheet lists Acetic Acid at 4-6%, the remainder is water. I noticed on the white vinegar label is listed acidity of 5%, but I don't know if that's acetic acid or something other acid.

The Austin's was $1.79 a quart.

The pistons all have letters written on them. Here's one with an 'H', they are in the 1-3-5-7 cylinders. 2-4 have 'G' and 6-8 have a 'J'.

Here are some pics of the markings I mentioned. Again, I probably should have taken more before I cleaned the block up.
