Why can't OEM LS blocks run the quarter-mile in 5 seconds?

Those Teksid blocks are built like brick shithouses. He runs 60 lbs of boost in that car. The aftermarket iron LSX race blocks would struggle at that point. Right now the quickest and fastest production LSx cars are 4.9x and 14x mph in the 1/8 or about 7.75 @ 180 in a 1/4 mile.

One of the quicker stock block LSx 1/8 mile cars out there.

One of the quickest LSx drag cars out there. 4.15 @ 185 in the 1/8 is about 6.60 @ 230 mph in the 1/4.

Because pushrods are outdated garbage

The aftermarket GM LSX race block is designed to reliably support about 2.5-3k hp. A typical turbo setup in the 400-434 cubic inch range will make that on 30-40 lbs of boost. Go ahead and try to cram 60 lbs of boost in but it's not going to like it. It's also pretty tough to compare drag car ETs, trap speeds, and incrementals without controlling for race weight and tire size/diameter.

Nice.

So what's the problem?

Based on the Mustang's ET and trap speed it has roughly 3k bhp. The LSx has more displacement and makes 3k bhp at lower boost numbers. Most people don't just throw money at components in drag racing at that level just to do it. It may not be the case that a stock block 6.0 in a 2,500 lb pro mod car couldn't make 3k hp and run 5.88. I'm not sure anyone has tried it because it doesn't really make sense given the major rule sets.
But even the quickest aftermarket LSx cars seem to be stuck in the 6.50s in the 1/4 albeit considerably heavier than 2,500 lbs.

>lbeit considerably heavier than 2,500 lbs.
I tought the benefit of pushrods was being lighter?
Hudson Hill
It's not necessarily the engine causing the extra weight, but we are talking about a cast iron block versus a cast aluminum block. The LSx cars run in a different rule set. A lot of pro mod style drag racing these days has minimum weights based on displacement and power adder. Not to mention often times the cars must be built different or meet certain specs.

>60lbs of boost on stock heads and block
How is this possible
Eli Allen
Because you didn't force enough air into the engine block... or you're not using top fuel
Anthony Edwards
Brick shithouse design. Mihovetz has been drag racing the 4.6 since it came out. He ran 6 flat on the stock crank too. According to his team they've had 0 4.6 engine failures drag racing in over 25 years.
Hudson Myers
why isn't the engine over the rear wheels?
Blake Edwards
Pro mod car. That's not allowed.

top fuel does not use oem blocks

filling the block with cement
