I have been looking for parts for the Chevy II four banger engine? Anybody know who carries any of the parts. Looking for any type of speed parts etc. That sounded like an oxy*****. Thanks in advance John
Here's intake and headers http://www.cliffordperformance.net/...?Screen=CTGY&Store_Code=CP&Category_Code=C250
If you can use used parts, keep a eye on the cl***ifieds here: http://www.midgetmadness.com/ race engines/parts show up there on occasion.
comp or lunati (can't remember which catalog i was just looking at...) had a couple cams listed... brandon
The chevyII 4 cyl was used in boats. Mercury Marine modified them to displace around 180 cubic inches in some versions. They had some dress up parts like alum side cover and valve cover. I think they also had some intake manifolds that used bigger carbs.
GM STILL builds the Chevy II 4 cylinder engine! It is now 181 cubic inches! and it can come fuel injected. http://www.gm.com/experience/technology/gmpowertrain/engines/specialized/marine/2009_3000_Marine.pdf http://www.gm.com/experience/technology/gmpowertrain/engines/specialized/marine/marine_engines.jsp http://www.gm.com/experience/techno...ecialized/industrial/2009_3000_Industrial.pdf SpecificationsVortec 3000Industrial Engine© 2008 General Motors Corporation PRINTED IN U.S.A. 01/31/08GM PowertrainType: 3.0L I4 Displacement: 181 cid (2966.59 cc) Engine Orientation: Longitudinal Compression Ratio: 10.5:1 (LW6), 9.2:1 (LMX, High CR) 8.25:1 (LMX, Low CR) Valve Configuration: Pushrod Actuated Overhead Valves (2 valves per cylinder) ***embly Site: Toluca, Mexico Valve Lifters: Hydraulic Flat Tappet Firing Order: 1 - 3 - 4 - 2 Bore x Stroke: 101.60 x 91.44 mm Bore Center: 112.26 mm Bore Area: 324.29 cm² Fuel System: MPFI Fuel Rail and Injectors (LMX) N/A (LW6) Fuel Type: LMX: Gasoline (MPFI) LW6: Propane, Natural Gas Horsepower:94 hp (70 kW) @ 3200 rpm (MPFI: Gasoline (LMX)) Low CR 93 hp (69 kW) @ 3000 rpm (MPFI: Gasoline (LMX)) High CR 73 hp (54 kW) @ 2200 rpm (Natural Gas: (LW6)) 64 hp (48 kW) @ 1800 rpm (Propane: (LW6))Torque:188 lb-ft (255 Nm) @ 1800 rpm (Propane: (LW6)) 178 lb-ft (241 Nm) @ 1600 rpm (Nat.

here is a turbo manifold. it is the real deal. http://cgi.ebay.com/ebaymotors/ws/e...m=280250673462&ssPageName=STRK:MESE:IT&ih=018
If you're lookin to build HP find yourself a Mercruiser boat intake. They came in 120 hp and 140 hp models. That bieng 153 cu. in. and 181 cu. in. respectively. I found a boat engine that had not been winterized properly and had a cracked block but the head was still good. The little Chevy II engines were only rated at 90 hp. While your at it ****** the intake and cut it down for a cheap solution to a high priced aftermarket one. Here's one I did a while back. http://www.jalopyjournal.com/forum/showthread.php?t=112313&highlight=I+put+my+intake Also zero decking the block and a little cam really wakes the little guys up. I spoke with Joe Mondello once and he said he used to build well over 300 hp out of these engines for dirt track guys.
Although there have been a couple of old Rod and Custom article, annual No. 9 (pp 64-65), and one other, articles to suggest that the '77-'79 Pontiac Iron Duke was another incarnation of the Chevy II engine, they are a different beast. The simple OHV pushrod design, Chevy "barn" bellhousing, and 4.4 bore spacing were similar, but that's about where it ends. I've attached head gasket pics to show the radical differences. And I tossed in a 1999 Corvette LS head just for fun (No, the ten-bolt pattern is way different). EDIT: Let's see if I can upload those images without crashing Explorer again...
I saw this one at Pleasanton Goodguys the other weekend. small block head. the bores line up but you need to play with the bolts a bit.
The KRP blocks can be ordered inany version and bore spacing to matchthe Pontiac sd head, sbc, sbf, and even the dodge head. theyalso have the standard Chevy bellhousing bolt pattern. they purchased the tooling and rights from GM. I have a KRP motor with a Brodix 10x aluminum SBF head. i plan on running it in a T project.
Right-on! Sweet car! I wonder if anyone has done a Tech Article on redrilling the block -- I've heard it required welding cast iron, so a bit out of reach for most of us. Here are a couple more Mercruiser gasket shots... I did read that the earliest (77-79) pan gasket may interchange with the Chevy II, though.
Also a pretty good source is OpenWheelMarketplace.com,they have a midget racing section,guys are still running the later IronDuke Pontiacs now,and there's still guys using the earlier ones in antiques....lots of stuff out there,just got a later Duke with injection,etc for not stupid money,for my modified T.
