I’m looking forward to seeing how your engine comes out. I may go nuts on the challenge car post challenge too.

UPDATE:
Well here is all the rotating assembly as well as the new heads. less words, more pics here we go!
Block should be back from machine shop next week then.....assembly begins!
Looks like a pretty big power upgrade. What are you going to use for air and fuel?
In reply to AnthonyGS :
Car was upgraded to 255lph pump and 24lb injectors when I swapped to the GT40's so I should be able to manage with that. Intake will be ported, a lot more! hopefully get as much as i can out of the GT40 Explorer intake as I can
Please detail your pushrod length measuring technique. I am assembling a nice little 306 for my Mustang, I have the adjustable rod and some weak springs to start with.
In reply to akylekoz :
will do, I'll be doing it with an adjustable so it'll be the same. Its going to be awhile til I get there tho ugh
If you weren't in the great white North I have a 302 short block I'd give you
In reply to Opti :
Damn, yeah from Texas it be one hell of a shipping bill but thanks anyways. I managed to use the block I had although its now bored to .040 which is the absolute limit of so this will be the last rebuild for it.
The machine shop is quoting me 375-420hp based off my heads, cam. Tune and my intake porting skills will determine where abouts that will land. I'll be starting on porting the intake probably in the next month or so, the intake is sitting on my kitchen floor waiting to have the fuel rails, and coolant tube removed. My goal is to achieve that magic number of 1 rwhp per 1ci. so goal is 333hp to the tires and I'll be happy, anything better is gravy Ill already be adding an additional 113rwhp at that number to what it was the weekend before the motor was pulled.
the exhaust I'm planning to tig weld, new BBK longtubes, cutting off the ball flange and welding on a v-band clamp. then running the flex joint, vibrant resonators, x-pipe and the Black Widow Venom mufflers, hopefully being able to use my flowmaster over-axle and tips again. Should hopefully keep the sound at no louder then what it already was.
For handling this year Im going to pull out the front 3/8" wheel spacers to hopefully assist with getting rid of the tire rub that Ive had in long and sharp corners. Estimating that I'll be driving the car into the corner a lot harder with the increase in power, finally utilizing my new brakes, with the ducts on. We shall see if the car can be made faster without spending money

Engine porn pics are hard to beat .........er that doesn't sound quite right.....and Happy New Year to you and Ms.Astre!!!
In reply to 759NRNG :
Haha, I had to read that twice, it didn't sound right! Lol. Thanks happy New Year to you as well from the great white North.
Happy she let me get all these parts, I was genuinely concerned she was going to be quicker then me when her Astre is complete lol
Brah keep an eye on Ms. Astre.....when you least expect it she may have acquired a special something (not a new saddle) that may give you pause when her 'ride' finally fires up.....shoot any woman that twists wrenches in the 'DEAD FREEKIN' COLD ' of winter has to be admired and respected....peace out...
In reply to 759NRNG :
Shes a unoptainium unicorn thats for sure :)
UPDATE:
Well for all the things I have built in the kitchen a motor has not been one of them, joined the Kitchen motor build club K.M.B.C today. Heres the start
assembling the floating pistons and rods with those pesky spiral locks. Also test fitting the windage tray again to see if I'll be having any issues with the dipstick, I shouldnt have any, might require a small amount of grinding to make 100% sure.
Block over the last week spent time at work, getting a nice coat or POR15 corporate ford blue, its a bit darker than it should be but it matches the car so its good!
black epoxy primer
Gotta say the bores on a 302 block look utterly massive for the size of the block.
In reply to Rushcanuck :
They are big for the block size. Thats also why the LS series has similar design and broke away from the chevy small block design.
In reply to AnthonyGS :
I always thought an LS was essentially a modern redesign of a windsor block with the canted valve cleveland heads....aka 69/70 boss 302. Ive even seen where a guy has made a set of LS heads bolt onto a windsor block, with a custom grind cam to reverse the intakes and exhausts, as well as a custom welded intake. was a cool bit of hot rodding
UPDATE:
Tig welded the v-band clamp collectors as well as the o2 sensor bungs
Rushcanuck said:[...]
I might have missed it earlier in the thread, but why do you have two O2 bungs on the same collector? And as a follow-up to that; are you worried about getting a skewed reading on the downstream one due to the upstream one interrupting the flow? Seems like having them offset around the collector would help prevent any such interference.
In reply to artur1808 :
Second is for my wideband gauge. Typically a single sensir gauge should be placed on the driverside header, as its where the fuel rail ends, typically that's side is the first to go lean. I was a bit worried about one being immediately after but basing where the floor, subframe connector, bellhousing/transmission and the ground is going to be I was forced to place it in line or slightly in a different angle. And after the flange is going to get in the way of the transmission crossmember. It may have to be moved later on but for now this will do.
UPDATE:
So its been a long painful path but I've finally got all the rings filed to size. Im waiting on a tapered ring compressor from summit at the moment as I couldnt get the band style to work for me.
crank is in, all torqued to spec.
Also plugged a piston in without rings to check rod clearance with the plastigage
also did a bit of painting, testing out my new 3m accuspray. Got all new stainless allen head cap bolts for the entire motor. should make it look sharp!
Also made my own X-pipe for when I start piecing together the exhaust
Lastly... port work on my poor little GT40 intake has commenced. Im hoping to make this intake work decently with the new heads, meaning port matching the larger gaskets. As well as trying to straighten the flow a bit more. hopefully without cutting through and creating myself the headache of welding aluminum
In reply to Agent98 :
All true but the LS is a rapid departure from the architecture of GM V8s and has exactly the same general architecture of the original SBF. Denying that is laughable. That’s not saying the LS isn’t the best pushrod engine ever; it is. It still has far more in common with a pushrod 5.0 than any engine Chevy built prior to the LS.
Update:
shortblock....built!
Now its onto the frustrating process of getting the windage tray to work with the dipstick, oil pump, and pickup.... yippee
For the first time in awhile I shoveled the snow out away from the tent to take a look at the car. was almost 3 feet of snow and still was a good drop into the bare ground in the tent. Stuck on a pair of new decals for next year
Since its back to winter, I figured Id start posting more again and updating although Ive noticed all my photos are not functioning anymore. I guess facebook probably changed there viewing rules again gah... How do others post photos on here?
Will probably go through and edit each post if possible and make this all viewable first haha
-Thanks in advance
I usually upload photos directly to the forum with the image button, two to the left of the emoji button...could be tedious for large quantities of images though. Imgur.com is a seemingly reliable image host as well.
