This sounds like its going to be a fun one. How many cubes as a stroker?
What pistons will you use?
As for the lumps, you know me, a sawszall will do. My install video will work for the PES also. Tom

It's great to see all the interest in the the 153/181 L4 engine. I may as well throw in my two cents. I am currently building a 153 for a front engine dragster. It has been an education, and I'm willing to share what I have learned, and will learn. I had the head modified by Mike Kirby at Sissel's Automotive. He did all the good stuff: Lump ports, port and chamber work, 1.94/1.60 stainless valves, screw in studs, guide plates, springs, retainers, etc. Mike's work is top shelf, and he is one heck of a nice guy. He is the final word when it comes to head work on the L4/L6 engine series. I highly recommend him. I am working on the short block now. We'll end up with around 12.5/1 compression, and have a custom cam ground to match what we're doing. The object of this whole exercise is to run at our local 1/8 mile strip in brackets, and make some nostalgia and inline events as well. Of course, the main objective is to have fun. I'll post some pics of the head, and give more details later.

Another quick note. A good distributer is readily available for the 153/181. The big cap HEI from the 77-78 151 is a direct bolt-in. These were in 77-78 Chev Monza, Pontiac Sunbird, etc. A-1 Cardone part # is 301490. Hope this helps those having problems finding a decent ignition system.

Ok,
Closer to using a 153 or 181 in the farm buggy. Picked up a nice 4 bbl LPgas conversion at a swapmeet this weekend. Complete and working. Going to put this on the buggy.
Need help with distributors. The industrial 181 and merc 120/ 140 hp engines used no vacum advance and maybe not even mechanical advance.
Like to run a HEI with vac advance. What application from the 70's/ 80's car will fit and have both advance options? I think 151 dist will fit if they were from the front dist location, like the inline 6 big brothers. Tom
Also need a Clifford intake for the 153 4 cyl engine.

I found some crank casting numbers today.
153 '62-'02 (must include marine engines) These all have 2 piece rear seals, 2.0" rod pins, and 3.25" stroke. # 3788522, #3793082, #5743014
181 '60-'99 2 piece rear seal, 2.1" rod pin, and 3.60" stroke. #N393775N, #N9341352
181 '60-'99 1 piece rear seal, 2.1" rod pin, 3.60" stroke, uses 1"wide rod. #140966
181 "00-'08 1 piece rear seal, 2.1" rod pin, 3.60" stroke, uses .940 wide rod has a torque converter hole. (?) #93436083
181 "00-"08 1 piece rear seal, 2.1" rod pin, 3.60" stroke, uses .940 wide rod has no torque converter hole. (?) #93436083
The .940 rod width of the last two cranks seems the mean that they could be used with SBC rods that has the 2.1 bore. The ones with 1 piece rear seal could be used in a 151. That would add .60" to stroke. Which makes the Iron Duke a 181.

That's cool to hear. I have a 2004 181 from a forklift. SBC rods will interchange? WOW, maybe this one will get built up for alittle 4 cyl power. The 4" bore allows the use of common SBC pistons too. Already did that on another. Tom
