1st time i tried to get a shop to cut a 5.7 Hemi out to 4in, they asked me to leave...........I went bought a Van Norman 944s.....takes 8 passes per cylinder to get to where I want.. some times you got to do what you got to do.
@@beckbuilt3209 the 1st one was .185 , for boost I wouldn't do it myself..... some of these 03-08 5.7 G3s can be as thick as .300but average is closer to .250, if you find a nice one you can go out to 6.1 bore (4.055) biggest I've gone was 4.06 and had .100 left at it's thinnest which was between #6&8 , that block I filled the bottom 2 inches of the jacket. used a 6.4 crank(trimed the nose , 3.72 stroke) and built a 385ci . ported the F#@& out of the 04 heads, opened the port up to P7 specs 2.125 Intake and 1.60 Ex valves , match the exhaust port sides and roof to the "round" tube headers leave the floor flat , I used a prefix cascar intake ,welded the opening to match the P7 port ,it makes about 620hp NA, uses Howards .623/.600 . In my uncles Video on G3 oiling (th-cam.com/video/Gl5a5kY1D0c/w-d-xo.html ) about 5min mark he shows how thick they are with one he blew up at about 1000hp on a stock cast crank.
@@TaylorJensen-ys2cv Very good information, had no clue they were that thick. I need to invest in some equipment to measure thickness. What do you recommended? And awesome power btw
@@beckbuilt3209 I got lucky my uncle gave me his old Dakota PR-82 when he bought a PR9 , those are about 1200ish , I was using this GM100 I bought of of E-bay , $80 someodd bucks, it's close to the Dakota, close enough for the "home DIY guy" if you are doing a max bore type build...No , but just a .010/.030 it's good enough ....... trick with the Cheapo ones is to contour the reader to the cylinder wall.
Nice 944s Beck.
Good find.
You will have fun boring your own blocks.
Thanks for sharing. 👍
I have the same bar absolutely love the little thing
Very cool video. We use a van normal 777s
Thank you, that’s what I was looking for but this one popped up pretty cheap
Sweet a bore cutter from the 50's 😅
Round hole is a round hole

How thick were the cylinder walls after?
