$/HP starts getting really high when you abandon the stock bottom end. For example, adding $2000 heads and cam on a stock shortblock can add 100rwhp, or $20/hp. Going to a 383 with that same top...

IIRC the TPI heads were heavy on exhaust flow which is why the LPE 219/219 cam and other cams with even split were created.

My god that is immaculate. The black and white photo makes the corner lense look clear or tinted and looks sick.

There's not enough details to give an accurate guess. What do the heads flow? What is your quench? Who is tuning it? Are you using 1.5/1.5/3mm rings or thick ringed heavy old sbc pistons and...

Pfffff, 5800? 6300 is more like it. And you have to go to 6300 on the stock heads and cam with long tubes for fastest time down the track. 6300 is the rule of thumb for self aligning rockers, rule...

It's really depressing that I posted your build thread on another forum to help someone understand what it takes to build something like this, then I curiously click on the last page since it's...

I am lacking time to rebuild my motor, looking for an lt1 that's rebuilt with ARP rod bolts, basically any LTx shortblock ready for 7000rpm. Looking to spend $1000 or less, email me at...

I love this thread. I'm learning so much about these little details most people do not take the time to document, thank you for that. Keep it up, I hope we can all meet up at an east coast LTx meet...

Sweet thanks

You are high as hell if you think that Chinese cast cranks are stronger than GM cast cranks. I am an engineer too, I see why you would think it by the numbers, but if you think the thousands of...

0.026" head gasket and -5 to -7cc flat tops, but make sure they at LEAST as light as stock, but shoot for lighter. Either way, if you put in new pistons,...

I'd get a different cam. Custom grind and those heads could add a bit.

Anyone have a link to how they did this? I hate pulling the passenger valve cover with the factory spot and want to keep power steering.

Pull a head, or use a harbor freight camera thing and peak inside a spark plug hole. Are the plugs out when you try to turn it over? If there is debris in there, and it scarred a wall, and you are...

You said "stock stroke crank", but is it a STOCK crank? Or an eagle cast crank? Wobbling damper and vibration has been seen alot when an eagle cast crank snaps at the front.

Since my heater box is gone and I have so much room I wanted to put it on the passenger frame rail behind the wheel, in front of the firewall. I just need to get longer cables and some sort of heat...

With no vacuum it goes to max, if you have less than 40 with the vacuum unhooked and a new fuel pump I'd suspect the little rubber line in the tank has a crack or hole.

Ls7 lifters have had way too many failures to give me any kind of warm and fuzzy, I'd either source a high mile cheap maybe rid knock lt1 off Craigslist and rob those lifters and cam and part out the...

What brand opti? Could be bad out of the box if its a Chinese crappy one, or the rotor could have come loose and torn itself apart. Id pull and inspect, and maybe replace or at least ohm out the...

If your factory lifters are fine, use them over the LS7s, the ls7s have had a ton of failures.

Correct me if I'm wrong but isn't there a reason standard batteries need to stand up? Optima advertises that THEIRS can go on its side or upside down because its sealed, but I always thought with a...

CSR 6 years still going.

Like catmainge said, if you are not going to spray too much go 396, if you are spraying you want a bigger top of the piston, so you need shorter rods, a 5.85 or 6" rod will leave the top of the...

Edelbrock intake is only a viable option for lt4 heads if you can't find a real lt4 intake, or don't want to have the flange on an lt1 intake reworked to fit the lt4 heads. Like Lloyd said, the...
