Another 2110 build *Head Advise Needed*

Everyone thank your for the input. I'm begging to get a headache on how many choices I do have. Shocked

John, I wan't something that will have a bit of everything. low end torque and RPM power. I'm not looking for a 7000 rpm engine. But I don't want a tractor. I think I'm saying is I want to have my cake and eat it too. Is this not possible or is it build a tractor or full blown engine. That is where i'm confused. Mostly I'll be cruising at 45 - 50 mph. It will be stock 66 trans with 205/65/15 tires so rpms 2500 or so right now. But I do want something when I drop the hammer it will pull nicely. I'm sorry don't have a engine vocabulary so bare with me.

RC, your input also please and of course the Samba

with an Engle 120 or Web 110 with either 1.1s or 1.25s will be an easy to build and powerful engine. If you go the ratio rocker route (86B) it will basically keep pulling, and pull harder, with a longer living valvetrain.

Any cam in the 255-260 duration @ .050" will work well.

This is a textbook "big engine" combo that works very well, Mark Herbert (RIP) promoted this one a lot.

Bare with me then an Engle 125 with 1.25 rockers will pull at higher RPMs? Will I have enough torque at the lower RPM range in order to get in and out of traffic for example and also have the engine pull through the higher RPMs?

the 125 is just harder on the valvetrain.

we have pretty good descriptions for our cams.

Ok so going ratio rockers is the way to go. Now is this something that I can learn?? or does it take an engineer by my side?? I'm willing to buy the measuring tools. Now for the other question is 1.25 rockers easier then 1.4 rockers or the same measuring techniques?

Few things has changed now on my build: Changing the stock to ratio rockers, rods are going to be 5.5, push rods are now need for the ratio rockers.

Keep the info coming I'm here and taking notes. Thank you all

The ACN road warrior heads look and sound like nice street heads.I would think they would also work well with a web 86a for a little better bottom end.

Try running street eliminators and a fk 10 or 87 and bump the comp to 10.5 or 11.

with a 5.5 rod. wont you have like a positive .200" deck height. wont that get into your engine width issues, you dont want to encounter?

yes depending on the bearing style you run i:e chevy porsche

I would not run 5.5 rods with an 82 crank, you run 5.5 rods with a 78 crank. Rod length should be selected to keep the deck height and engine width in mind.

The L5s are good for over 180hp with an FK-8 or 86B. With a 120, 125, or 109 you are still looking at 150-160.

And don't let people scare you with "no low end" garbage. It is true there will be "no low end" compared to the top end, but if you overlayed the HP/Torque curves along with a stock 1600DP, you'd see you had more low end than stock. So it will still be quite easy to drive. The milder the cam the easier to putt putt around. A 120 is a pretty mild cam if you have a 2275 with some L5s/Dual 44s/1 5/8" Exhaust, for example.

If you want to play it safe, either get

L5s, 120 and 1.1s or 1.25s
or
L5s, FK-8 or 86B, and 1.4s.

Both require dual springs, and both will haul @$$.

The ratio rocker one will cost $150 more, but I think that's well spent.

John: Thanks for the feed back. What lenth connecting rods do you recomend then?

It seems that going with 1.4 rocker is the way to go. Even though my concern is my ability of getting the geometry right Shocked

i was pretty much asking questions as well, i encountered a .031" positive deck, with 82 stroke and 5.4 rods. cant imagine having to deal with a .130" positive deck. i ordered some custom cylinder shims from rimco, 75$..ouch!!!

Yeah I noticed you kept your mouth shut but I'm not one to let others take my lumps. All of us are human and I'm not one of the engine God's who refuse to ever admit making a mistake. I may post a lot here but it isn't about ego or superiority in any way for me....it's about helping others and promoting business and I never hid that fact from my very first post. Post enough and you're going to make a mistake sometimes. Try to be chief cook and bottle washer and quoter and machinist and builder and receptionist and tech line and you will make a mistake sometimes.....today was one of those times. That's why I don't take calls in the middle of machining or assembly.
