94 or 90.5

Post by Passatman » Thu May 09, 2002 10:40 am

This question is for muffler mike. I intend to use a 82mm crank car on the road but, i don't have a clue as to which piston and sleeve to use. I want to use 94mm and make a killer engine but can this engine be reliable say (50K-80K). I have heard people use 94mm on daily driven cars. Can a engine with 90.5mm make 150HP-180HP and can you give me the specifications for this engine.

There is about 0 reliability difference between 90.5's and 94's.

i have a 2110 with the following specs:

82mm Welded
90.5 p/c
en120 cam
CBs 044 heads with mild porting 42x37.5 valves
dual 44s
1 5/8" merged header
8.8:1 comp

The dyno program I used says I make 165 hp @4250 rpms. That seems to feel pretty accurate when I drive. Although if I had it to do over I would probably knock the cam down to a 110 to get a little more low end.

I just finished building it so i'm not sure about reliability, but I built it pretty good so other than occasional head freshening it should last a while if I don't drive like a psycho.

Hey lee we have to keep in touch. I would definately want to know what this engine does in the reliability department.

No guesstimates here....

I have made 180BHP on the dyno for a customer that drives his car 65 miles per day each way and it is equipped with 94s...

I have seen them last over 65K on an engine with no maintenance performed, and still be in great shape, a new set of rings and hone job and I slapped them in my beater 138BHP 1914..

Im really the last person you want to ask about longevity and reliability, as i dont worry about that.
But i can tell you i know people that have run the piss out of those 94's with zero problems. and i dont see why you couldnt run them for quite a long time. Assuming you take care of them.
I have rehoned 1 set when i had some leak down issues. but i think this came from blasting the motor down the track with no cooling late in the day and late in eliminations, pop the fan belt back on, and blast back to the front, giving it a quick blast of cold air when they were real hot to begin with. after i went into racing with no fan or tin of any sort, they stayed round for years. Now i race with a fan on, and havent noticed any problems as of yet, but i am now running the century cylinders too.
weather that makes a difference or not?????

FWIW, I here's the low-down on my engine.

2110, 44 idf's, Scat C35 (just a hair more than an Engle 110), 040 heads with 42x37 valves, in a full weight '68 sedan. I have over 4000 miles on it which have been very reliable. Last weekend I took a road trip of about 160 miles each way, as well as some substantial beating while there. The trip each way was done without stopping, and going 70-75 mph most of the way. I feel I built my engine well enough that it could take 180+ hp without breaking. So with an estimated 140-150 hp, and 1000 fewer RPM, it's living a relatively easy life.

Some of my friends give me $hit about the smallish cam, but on the other hand I don't see them driving their car across Michigan, either!

What's up lee. I would like to know the benifits of using a 82mm crank with chevy journals.

Chevy journals just allow less case clearancing because they are smaller than a VW. For an 82, its not necessary.
