Making "Ward's Ten Best Engines" means about as much as winning a Motor Trend "...of the year" award.

You were saying?

Far and away the best follower offered for the Modular 2V/4V is the Ford GT/GT500 "supercar" follower photographed above. In spite of appearance they are fully interchangeable with the followers in your photo (see lower follower in 2nd photo) and maintain the same rocker ratio. They manage to...

Those stock hydraulic lash adjusters and roller followers (specifically the ones that came in the 05/06 Ford GT and 2007-2014 GT500) have been used reliably in applications spinning well over 10,000 rpm and making upwards of 3200 HP. ARCO is simply off base on this topic

I suspect oil pressures will prove to be pretty close to ideal with any oil in the 4.0+ HTHS viscosity range. Since 40 weights fall within the operational viscosity window Morel specs it seems the obvious solution would be start with a relatively high HTHS viscosity 40-weight oil and then fine...

The 4.4 HTHS will probably also keep those mains happy as their clearances that will grow to ~ .0035"+ at temp

The Mustang's Gen 3 5.0 offers a wider working power-band with superior average power to the LT1 - that's part of the reason why the Gen 3 5.0 Mustang will typically walk away from a 6th Gen SS on the top end despite being a heavier car that's also down 70 cubic inches. Regarding the LS3...

RWD = right wheel drive :)

Most of the current pushrod engines do have VVT. In more displacement limited 4 and 6 cylinder applications I believe it really does come down to power density more than anything.

True

Because pushrod engines have poor power density compared to any even remotely well executed 4-valve per cylinder engine. 1. Compared to a 4-valve/cyl engine? Only if the LS has a significant displacement advantage 2. No they don't - method of valve actuation has zero impact on where any...

Best vehicle Toyota makes

It seems straight 6s are making a comeback, a good thing IMO

So what? This engine has TSBs out relating balance shaft concerns/howling.

Long stroke 4 cylinder reliant on a balance shaft that has already posed issues in service, 2 piece sliding camshaft, no port injectors, owners complaining of poor real world fuel mileage. I wouldn't touch this thing with a 10 foot pole personally.

It's still a 4V engine is it not? I'm not sure why having 2 separate camshafts would help it rev any faster than having 1. I'd wager they switched to DOHC primarily to gain the benefits of independent intake and exhaust cam phasing -- the ability to constantly change valve overlap has a lot...

Well, they do have all of that except the drink order button is actually a massage button...

A lot of DOHC valve-trains use roller followers paired with hydraulic lash adjusters that many people refer to as lifters. I believe that is what he was referring to
