My l48 Project Thread
Update: after being so across the board on what I want it was time to make a decision. I talked with a guy and machine shop who helped me build a kit. We decided best route is to buy a new 350 block with all machine work done, bearings installed, etc. To pair with it were going to put in a eagle bottom end kit. It is all one piece main seal with a 4 bolt main too. Then for top end were putting on vortec hd truck heads with 180cc flow and 64cc chambers due to budget. So to break it down
This is my plan:
1)buy bare block 383 engine.................................. Summit racing http://www.summitracing.com/parts/su...make/chevrolet
2)install new eagle 383 bottom end.........................Summit racing http://www.summitracing.com/parts/es...3068/overview/
3)install Vortec 180cc intake runner & 64cc heads.....Craigslist
4)install Summit cam..................................... ........Summit racing http://www.summitracing.com/parts/sum-1104
4)Take it to ShoMeSpeed who is going to re jet/re curve it and dyno
5)pull l48
6)paint engine bay
7)drop new engine in
The tools I need to buy are:
1)Engine hoist ..................(bought)
2)Engine stand .................(bought)
3)torque wrench ...............(bought)
5)cam install tool ..............(bought)
The Parts I already have are as follows:
Lunati Lifters
Felpro gasket set
timing chain
re curve kit
lifters
rocker arms oem
750cfm carb
The parts I need:
summit cam 1104
summit 383 bare block
scat bottom end kit
arp bolt set
Felpro .015 head gasket
Vortec heads
push rods
break in lube for cam etc
harmonic balancer
torque convertor
stroker oil pan
stroker oil pump and pickup
Ill be updating on every part I get and step I make further to completion. Also pics of the new vette will be up sometime too.
I am picking up the heads Tuesday and buying the block from summit hopefully the 12th

Well Ive finished all the major details and I know what route I'm going to take. I will be posting pictures of everything and all parts and going updates probably every two weeks. Ill also probably be asking tons of questions on here. So here goes.
This is my plan:
1)Pull engine
2)Paint engine bay
3) disassemble top end off l48
4) install new top end
5) Take it to Sho mespeed who is going to rejet/recurve it and dyno
6) drop motor back in
I want to everything but step 5 on my own. I have tons of friends who know a ton and my neighbor is a mechanic owner. I also have you guys so I'm fairly confident I can get it done in 2 months average time.
The tools I need to buy are:
1)Engine hoist
2)Engine stand
3)torque wrench
4)push rod checker
5)cam install tool
The Parts I already have are as follows:
Lunati voodo cam 262/268
Felpro gasket set
timing chain
recurve kit
performer intake manifold
lifters
rocker arms oem
The parts I need
Felpro .015 head gasket
Dart shp 64cc heads
push rods
break in lube for cam etc
If anyone has been following my heads choice Ive decided to sit on the money tree and save up for quality heads from apr. I cant afford to spend 200 less and get a crap product.
Ill be updating on every part I get and step I make further to completion. Also pics of the new vette will be up sometime too.
Now question
Will I have to set the valves? Is this basically the last step in assembly?

and how do you adjust valve lash?
Also when I install the cam and put the timing chain on. Is there a special position the crank and pistons are suppose to be at in the block or can i just put the dot to dot on the timing chain gears no matter where the pistons are positioned and thats it?

gotcha. I was told that you should not turn the crank though after pulling the distributor. So how should I go about getting piston #1 (assuming its the first piston on the right when standing at the front of car ) at the top of its compression stroke?

The only way you can get the dots to line up properly is if the rotating assembly is properly positioned, so it's not something you need to worry about. What you need is to study the basics. Get a book on rebuilding a chevy small block and study it. Notice I didn't say read it, I said study it. Good luck,

Reason is i can get forged mahle pistons that require a .060 bore. I read that .060 bore was max. Maybe your right though because all the engine rotating assembly kits dont go over .030 bore.

I just purchased the heads from a guy off craigslist. I go to pick them up at the machine shop tuesday as they were getting cleaned, new seals, valve job, and guides. I only am paying $150. Great start for the budget build. I also just put in my order for the summit cam with 214 lift. Sold my lunati cam and intake. I need a vortec style intake if anyone has one ill buy it off you. Spread bore
