Both are extremely robust and reliable under street conditions IF, the specific engine is in known good condition.
But, the best features of this Lampredi engine is hidden. 86-87mm bore, short stroke with typical connecting rod to stroke ratio about 1.9 in a block with Siamesed cylinders, 5 main bearings and closed deck. These are the basics for any decent race engine.
We have LeMons race abused this engine for the first few years and it held up fine. But, it must be of known good condition as there are a number of details in assembly and related that allows this most excellent design to simply work so very well. An exxe with a proper race motor with about 105-110 Whp in a properly set up chassis, good driver has no problem keeping a race prepared Porsche 928 with a big V8 in check. This video was from about 5 years ago when this car still had the 1500cc Lampredi engine.

Parts, what parts specifically are wanted? ARP has hardware upgrades, Wiesco and others have pistons made to order, SCAT has con rods, Cometic has head gaskets and new cylinder heads are available. Due to the decades of production for this engine world wide, parts are often not too much of a problem.

What is the consensus on 1300 vs 1500? Reliability, and parts availability being my biggest concerns.
