sq creations: 499 Gram pistons? Dam those things are heavy. Good to see the progress with the build.


I guess they are on the heavier side. I looked up some comparisons after I saw this. I have had good luck with wiseco pistons in the past with other cars I've had. Hopefully the added weight will take the abuse better?



wiseco lists as 502grams

Arias 413grams

JE 395grams



A small update. The epic quest for lifters has come to an end. It only to 6 weeks and 2 companies to get them here but they arrived last night. I also got my intake manifold in. I hope to have a good update for you guys in day or two.

I also want to run an electric water pump to make setting up the pulley system easier, but it seems like the only ones for the LS motors are around $600.00. Way more than I'd be willing to spend. But it looks like you've got that figured out, and it should be super efficient.


More info plz.


My setup has the water pump attached to the radiator. you can see the 2 feed ports at the bottom and the 2 return ports in the opposite upper corner along with the upper vent tube port. 





Now for an update:

I got the coil brackets in and painted them along with the valve covers. I need to tap the holes for the coil bolts. I had to come up with a solution to the water crossover pipe that had been cut off. I ground flat the area, then drilled and taped for a fitting. I'm very happy with how it came out. As a last note for this entry I finally got the lifters in. Now I can put the heads on.

The moment I have been waiting for. I got the engine in the car. I installed the lifters and put the heads on. I got the flexplate on and now the motor is on the motor mounts. I still need to attach the torque converter. I also measured the push rods with a write up that TR posted and figured out I need 3.75 push rods. So I got those ordered. I also got the weiand intake and figured out that it wasn't going to work with my oil pressure sensor along with some negative reviews and resold it. I now have on order a GMPP single plane manifold and edelbrock elbow coming. It is similar to what the previous owner ran. I also read in gmhtp that a car gained 90hp on same boost (19psi) by switching from stock manifold.

I have the custom engine harness pretty much done now. I just need to put it in. I got my fuel rails in the mail. They are the professional products rails. I was concerned with the internal diameter but the bore is much larger than the -8AN fittings I'm using so it should be fine. I also got the coil brackets tapped for the coil bolts. The Comp 3.75 push rods and stock rocker arms are now installed under the valve covers. I also ordered my 4inch thick 1000hp intercooler. Hopefully that is the last big purchase I need to get this thing going.
