I'm with you all the way been turning wenches now for 25 years and wouldn't give it up for the world. Cast iron are the best

Aluminum blocks typically handle engine overheating conditions better than iron blocks. This is because aluminum has better thermal conductivity, meaning it can transfer heat away from the engine more efficiently than iron. Additionally, aluminum tends to have a lower coefficient of expansion, which reduces the risk of warping or cracking under extreme temperatures compared to iron. As a result, aluminum blocks are often preferred in high-performance engines or applications where heat management is crucial.

@@foch3 Having aluminum heads with an aluminum block is better in terms of overall heat dissipation and thermal expansion compatibility. This setup ensures similar thermal expansion characteristics, potentially reducing the risk of warping or damage during overheating. And cast iron blocks are predominantly used in the most powerful drag cars because of cast iron’s superior strength allowing it to take the repeated stress imposed on the engine without cracking or warping it.

Not crazy about the ai text to speach. But very concise and informative.

IIRC, the best material for engine blocks, especially for high performance production cars that are expected to be reliable, is CGI (Compacted Graphite Iron), an iron alloy used for NASCAR engines which are known for engines with even higher mean piston speeds than F-1 engines and cover longer race distances. It's not cheap though.

Cast iron for me, every time. I also prefer side valve engines, drum brakes and wooden wheels with iron tyres.

It depends on what you are using it for. For conventional passenger cars and trucks, cast iron is the best, as it is more durable and more resistant to damage. For racing, aluminum is better because it is so light. It can mean the difference between winning for a few inches or coming in second by a few inches. In racing, that is all the difference in the world.

Iron or aluminum/depends on what you use it for. I'm partial to all cast iron engines with carbs.

Cast iron blocks are a must for boosted engines and using nitrous. Alum. blocks are 100 lb. lighter and work well with cast iron bore sleeves. FORD sella high nickel cast iron engine blocks for super high stressed usage, but the price is frighting. But both GM and FORD use alum. blocks in all their V8's. Chrysler uses cast iron blocks in all their Hemi engines even the 5.7 and the 100 lb. weight is in the front of the vehicles, right where you don't want it ! Of course, cast iron blocks are cheaper to manufacture, so there is that !

wrong

Never had alloy always cast iron.

Whether the block be iron or aluminum, I would never, ever, want an engine with the head(s) being a different material than the block - iron block & aluminum head, or aluminum block & iron head - since the 2 metals expand & contract at different rates & amounts, blown head gaskets are a perpetual problem. Another is less well known: that of corrosion, the result of 2 different metals being bolted to each other, & especially with heat & a working fluid passing between & through them. Aluminum engine blocks are also less tolerant of over-torquing, & special attention must be observed, when considering the different torquing specifications during servicing or rebuilding the 2 different types of engines. Iron engines will tend to tolerate being overheated, better than aluminum engines; more often than not, if an aluminum engine suffers a catastrophic cooling system failure, it's best to simply replace it, as everything will likely be warped & lose its temper. Most of my experience working on engines, has been in the marine field, & those engines lead a hard life, usually being operated at full throttle & load - both iron & aluminum engines will fail, but for heavy duty & long life, especially for diesels, iron is best; for outboard engines, aluminum is best due to its inherent lighter weight. I've never seen engines with the 2 different metals making up the block & head(s) have as long & relatively trouble-free life, as those made of 1 or the other single metals. Aluminum also has an additional weakness, that of its reaction to the hot water-glycol mix, if there's ever a blown head gasket, & the coolant finding its way into the cylinder(s), &/ into the crankcase - aluminum is more reactive than iron. Ofc, the bearing materials of either type of engine, simply don't tolerate that water-glycol mix at all! Air-cooled engines do have their advantages & their place in certain applications.

@MikeM-oq9pz

No, aluminum blocks do not "burn oil' if proper oil change procedures are followed. It all depends on the piston ring material as some newer engines have piston rings that have low tension in the cylinder block, and these can cause oil burning problems at higher mileage moreso than the aluminum.
