SRT4 Engine & SRT10 engine

[s8taxatty]

Novice question time. I found a really cheap SRT4 engine to play with. Does the SRT 4 engine use OHV like the SRT 10 engine?:dontknow:

I hope I'm not embarrassing myself but I'm still learning and this is the best site by far!

Our engines are NOT OHV, the SRT 4 likely is sir

Yeah our engines are Over Head Valve(OHV) but the srt4 is DOHC....

And you work on these beasts? You should be ashamed sir LOL

So if the 10 is not an Over Head Valve engine, is it an Over Head Cam engine? or is there an other type? I am confused?

Haha kinda scary huh

I have never seen an engine that isn't Over Head Valve.

What you are wanting to know (most likely) is where the camshaft is. On the viper engine there is a single camshaft that is in the middle of the block and pushrods that actuate rockers that move the valves. The camshaft is driven by a timing-chain.

On the SRT-4 engine it is a Double Over Head Cam engine (DOHC). What that means is that the head contains two camshafts. One for intake valves and one for exhaust valves. The cams are driven by the crankshaft via a timing belt. And on some cars a timing chain. This allows the engineers to have more precise control of the valve duration and a reduction of weight.

Some engines have what is called a Single Over Head Cam engine (SOHC). That just means that there is a single camshaft in the head or head's and it controls the valves.

I would love to see a Viper engine with DOHC heads one day. That engine would LOOK SO UNBELIVABLY SICK!!!!

Thank you. I understand the distinction now. Lots of reading to do still.

I know he meant OHC but MAN it was funny to me.

any "flat head" engine is VIB.

Briggs & Straton & Ford come to mind real quick:rock::rock:

Hmmm 500cubic inch 2-stroke......

8V-71 Detroit= 568 c.i.d.

6V-92 Detroit= 552 c.i.d.

Bit on the heavy side though

A "flat head" or also known as "nail head" motor setup has intake and exhaust valves located within the block, not the head.

Check out your weed eater if you have one. 2 strokes and nail heads have no OHV or OHC...

"Got Torque"

Boxter style V12, 2 stroke with 4 ports per cylinder, forced induction :rock:

this ought to be good

the Buick "nail head" engine is an OHV 4-stroke engine:rock::rock::rock:
