What all did the machinist do, looking at your pictures its hard to tell, from my vantage point it does not look like it was line bored, cylinders don't look honed and the deck looks like it was not touched?
Be careful using a piston stop close to the edge of a piston above the ring grooves one wrong move (hitting the piston too hard) can actually fracture the top of the piston or weaken it and a chunk break off in the future.
What compression ratio did you choose at your elevation you can easily run 10:1 on pump gas?
This
Engine going into the Yellow car?
Heads are factory?
Was reading the other day GM makes a 427 SB that produces 750HP now but they are like 12k lol
Yes, its going into..
I'm just basically going back with the same combo I've run in the car since 1981. Only real difference is I'm using a later 2 bolt block @ .060 over the previous .030 66 4bolt block. My reason for the swap was that early block takes a grooved cam and a canister style oil filter, and as silly as it sounds, all these years those two items have always kind of drove me nuts.
He just did the basics on the block, Vat, Bore, squared up the deck, cam bearings & freeze plugs. He polished the crank & rebalanced the rotating assembly since the new pistons are .060 & 19 grams heavier. It will get the factory 840 rectangular port heads & 163 intake back on it as I want it to still look bone stock & original when you open the hood.
here is the old 427 with the heads & intake assembled with the old block right before I tore it down to start over.
The Engine is being built aside from the .060 bore, as a stock L-72 427. The compression will be factory 11.25 with my heads which is really too much for todays $hity gas but this is the combo i've always ran in the car & with a conservative tune I never had any problems. The only other real difference is I am going to try one of Comp cams s Nostalgia Grinds over the factory solid L-72 solid I have alway ran. Still going run a solid, but this cam claims to make power from 1800 - 6500 which on paper sounds great over the old cam that made power from 3200 - 6500, although low end was never an issue as you could blow the tires away if you stabbed it at 30mph anyway. lol.. But the new cam should hopefully make a bit more vacuum which will help with the hidden head lights and it has a tighter lash and in theory should be a tad easier on the valve train.
I was carful with the piston stop. Just used it to establish TDC (Top Dead Center) and get me degree wheel set up. My piston stop wouldn't reach all the way across the cylinder so I gad to do it that way. When assembling an Engine I always degree the cam with just one piston so it is easier to spin it over and you don't need to use as much strength trying to muscle it around and have good control over it.
Yeah they are making some stupid horse power with these stroker kits, I originally was going to build this as a 496 and had ordered a 4340 Scat Rotating assembly. After a month of getting the run around I pulled the plug and decided to just go back with the combo I had for half the price. I was always pleased with how it ran & as stupid as it sounds, I don't really care to make it any quicker, I've worked too hard on the car over the last few years to go run the snot out of it now. I just want when I get into the car & turn the key, & have it take me back to when I was a kid out terrorizing women & children with it.
