well i have a few questions to ask pertaining to engine specs. If you could please help me out i would be very thankful. Alright heres the questions.

6 cyl engine with the following specs.

1 bore is 3.750
2 stroke is 3.125
3 compressed head gasket thickness is 0.40
4 piston is 0.20 below the deck surface @TDC
5 cumbustion chamber is 45cc
6 Flat top pistons with 2 cc of valve relief
7 Crank center line to deck surface (deck height) is 9.145
8 Rod length 5.500

questions

1 what is the orginal size of the engine?
2 what is the compression ratio?
3 what is the compression height of piston?

Part 2

1 engine was bored to .030
2 new crank with an 1/8 inch more stroke
3 head was shaved and lost 3 cc of combustion chamber volume
4 block was decked .010
5 new pistons have a dish with 13cc of volume
6 new rod length is 5.650
7 head gasket thickness remains the same
8 piston is to remain .020 below the deck @ TDC

1 what is the new engine size?
2 what is the new compression ratio?
3 what is the compression height of new piston?
4 how much money did this engine cost to build? (estimate)

 

bump for some help

 

The original displacement was 3.4 L

I am assuming the gasket thickness and deck/piston height difference are 0.040" and 0.020" (forty and twenty thousandths respectively), not 0.4" and 0.2". If so, the original SCR was around 11.0-11.1:1. The height of the piston was 3.625" from the center of the pin to the crown.


New displacement: ~3.6 L
New SCR: 10.0:1
New piston height 3.465"

There are two many missing variables to even guess at the cost of the rebuild.

I made these very quickly, so someone may want to recheck.

 

any more answers?
