600+ is no big deal. You can always add four bolt caps if you want to..the blocks are identical.

I know of a guy running over 950 with a two bolt and studs, pretty stout 454 with a 350 shot of nitrous. I would almost be willing to bet a two bolt with studs is stronger than a four bolt with conventional bolts.

The Milodon kit doesn't include the rear main, I think the front is optional and it's two bolt.

I saw a thing about the 2 bolt small blocks having thicker webbing in the lower end and putting 4 bolt caps really increased the strength. Factoy SB's only had 4 bolts in the 2,3,and 4, with the front and rear still 2 bolts.
My 4 bolt BB has factory caps and are 4 bolt all the way thru.
Makes me wonder if maybe the 2 bolt BB's are a little thicker in the webs too. A 2 bolt block, refit for 4 bolt splayed caps might be the real answer.

Loots og good info here. But does anyone now how much HP it can take at it is?
Where to buy studs and caps, and how to install??
All that must be done in a machine shop, and cant by done by meself, will be werry expencive here in Norway. Most shops wont even take small tings, because they have so many large customers in line. (offshore industry are pressuring the prices up.)
So the bottom line is, that if i cant do it myself, i will reach the price of a crate engine real quick. And i was hopeng to spend around $3000 at max on the engine + some good headers (stans maybe???)
This is the projekt for next winter. The summer is time for driving an colecting info. The winter is the time for improving the car.

They have the splayed caps there. I suspect they will cost more than standard caps to install. Drilling them is a bit trickier. Splayed will give you even more strength/RPM than inline bolts. Definitely a job for a really good machine shop.

You could just put studs in and help some. All the hot rod parts houses have them.
Unless you're going racing every time you drive the 2 bolt should be fine.

Guys, he's looking to make sure he's safe with the 2-bolt if he adds the Edelbrock Performer package. I advised studs as insurance on another thread. Looks like the high cost of machining where he is makes the 4-bolt option too expensive for what he's planning, as long as he doesn't give it a shot or pressurize it...
Anyone agree???

For the Edelbrock package, a 2 bolt will work every bit as well as the 4 bolt. It's not he's going to add 300+ horsepower to it. No gas and a carb? No deal. Throw the package on and ENJOY!!!!!!!!!!

I will not use that car at a higher rpm than 5500 (automatic shifts before 5500 as it is anyway. \ TH400)
I was hoping that my engine would be ok with this package with modifications i dont need a machine shop for. if not, it will newer be installed. (the it will be: start to save money for crate engine.)
Does it sound ok to run this package if i have the stock 2 bolt w\ studs???

Why don't you find a local engine builder that you can trust and have him advise you on a performance package? Edelbrock's heads aren't bad but their cams are old school. Different car's weight, tranny, gearing, converter, etc. and intended useage will call for different camshafts. The cam for a 4000lbs Chevelle won't be the same as for a 3300lbs Corvette or a 5000lbs truck. If you can scrape funds together, go hydraulic roller. The AlGore faction of our government is doing all they can to remove all the additives from oil that provide adequate lubrication for flat tappet camshafts and as they do, you'll see more and more folks with flat cams, even those that have successful cam break-ins and thousands of miles of run time on them. One flattened cam lobe will cost you much more than the switch to hydraulic roller right now.

I helped run a drag boat about 15 years ago. It had a 427 with a 2 bolt main block and studs. Static compression ratio was 5.6-1 with an 8-71 Mooneyham blower making 22 pounds of boost. The motor made well over 1000 hp and turned 7500 rpm. Never had a mechanical failure, in fact the motor is in a pulling truck right now.
