.100 over slugs (NOT Weiscos)

-
What rod you talkin about usin? If you wanna use the 198 rod, look at some of the 2.2 Chrysler pistons. Remember, they start out at .045" over from a standard slant bore. So that means a .060" over 2.2 piston would be .105" over for a slant. You'd need to convert the metric oversizes, but they will come real close.

but would have to run 198 rods... hmm... but those pistons are pretty cheap arn't they?
 
Buddy of mine used late model GM V6 pistons on his slant. I'm not sure on the bore size. I do know they were way cheaper than the slant pistons.


Buddy of mine that built the motor checked his files.

For the slant that's bored .100

2.8 Ltr Chev piston. The bore size is 3.5039
Use 198 rod to make up piston height
The Chev pin bore is .905 and the slant is .901. You'll also have to bore the pin bore .004.


83-85 173 V6 part number 464P. Bore size is 3.5078. Using the 198 rod and boring out the pin bore you shoud have a deck height of .020. Shave the head accordingly to get the desired CR. You should end up with a slant of approximately 238 CI

well i have .110 of the head and .025 off the block lol... so would that make it 15:1?? LOL

but if i used a 225 rod and offset ground the crank i could get more cubes and have the comp i needed

I was thinking Chevy Vega pistons??

no i understood that its just i have .113 off the head and .030 off the block... so i dont want to switch over to the long rod and have a huge comp number that wont be streetable...
 
What is the bore and stroke of the engine at hand?

Then, look into other piston sites with these raw dimensions.

Egge machine can make some slugs for you that are cast. They should clock in cheaper than most other places charging $1,000 plus.

currerntly its a 3.480 with a stock 4.125... the piston is in the hole .157 with .030 off the block, 10:1 with .113 off the head... so im not looking to up the comp just get new slugs
 
75-80 Toyota 20R piston is an 88.40mm, thats a 3.4803". Check compressin height and pin diameter. Maybe a possibility as the 20R is a very popular motor and I bet there is some HP parts available...http://www.ebay.com/itm/75-80-Toyota-Celica-Corona-2-0L-20R-Piston-Ring-Set-/260789452121

here is a silvolite L6 piston to compare:
S6 225
3.7 L
3.400(IN)
86.4(MM)

CHRYSLER
ENGINE

1960-87

8.2

Cars through 1983, trucks through 1987. Flat top.

Comp. Ht. 1.740
Pin Dia..9012 Offset

Here is Toyota

L4-133.6
2189cc
3.484(IN)
88.5(MM) +0.1mm

TOYOTA
ENGINE

1975-80

8.4

20R engine. .110" crown.

Comp. Ht. 1.510
Pin Dia..8665 Offset

So they sit lower in the bore (bad unless you got tall rods) and the piston pin looks close enough to bore out to a L6 size (+.0347)

good reference page for available piston sizes http://webpages.charter.net/beckracing/silvtoc.htm
