Engine and Transmission Tech

Well just so everyone knows this is truely experimental and the goal is, and I know every one is looking at stroke and bore to make the biggest monster possible, but the goal is rpms so we are going over-square like the small japanese engines to build power in the strotosphere! The welding is to get more stud gripping depth/area, o-ring composite head gaskets, and with the heads, roller cam, roller rockers and an exhaust of 1-3/4 4 to 1 headers it should rev like crazy and have a very impressive power/torque band. I think if the thing holds up in high rpms then a really long stroke crank should not be an issue. This is an all around engine, drag, autocross & track engine. Right now it is almost assembled but not till late January will it possibly get completed and chucked on the dyno.

Was talkin to my machinist friend that I race with a couple times a year.. and he said to have a look at these..

Yeah, Totally. The bigger engine thing is just my hang up. LOL. Ya know what would be cool would be a Rover 289. 4" bore x 2.8" stroke. Like an AAR type o thing. That would rock.

Well, if you had a pair of OHC cylinder heads and needed to modify the block to accommodate the head bolts, this might be one way to get that done.

Yea,Yea,hint-hint. Set the hook in Granpa. "If you had say...a pair of 907 heads, mite-as-well go monster bore rite? An-an then it would clear Nic's "Tactor Pull" crank rite. Yea-thats-it, a 401",Rotus Brossum Gone Wild ! I doan tink-so, roverman.

LOL! It's WORKING!!! You beat me to it! I think the 907 head would work great as a deck girdle, right?! The other benefit is the lack of cam stress on the block. You are on to something there, Art.

Incidently, how much do those heads weigh? A 380 lbs. DOHC 401 V8 would be pretty bitchin'.

I just realized I never asked you about the source for the 4" liners, Mike.

say: "Fighting urge to do this..."

but-but.. if you do away with that cam shaft in the middle, would not it be possible with more stroke? nic?

Nix-If I tell you then I would have to take away all of your toys......I dont think you want me to do that.....do you? If this thing works I might let more out of the bag. I dont car what other British car owners think of this group......in my book you'all/we are ok!

Nic, try to remain...calm% "It's too much stroke when it becomes,un-gainly", ie. loss of control-Nic. Be-strong,not-"....", don't give in to the Dark-Side, Luke-Nic-whomever. BTW... their Waay to damn heavy for a hydrogen filled Vega! roverman.

Art, with the cam gone I'd be willing to bet you could go to at LEAST a 4" stroke. (402+?) And those big bores would let you completely unshroud the valves...

Yea...Thatz graaaaaaaaate,bigger is alwaaz better-rite? Let's remind ourselves, 907 heads will only flow 305 cfm.@ .45 lift in a 3.75 bore, waite-dammit, now I'm being Devil's advocate! roverman.

Mike. It's XMAS, MAN!! I already got this. Yup that IS an actual lump of coal:

Nix-You are too much! I LUV IT!

Nic ol' chum, I tried to tell ya, "overstrokin" would only lead to trouble. Now you you get to take your "lumps" and no toys ! Best you can hope for, is get Superman to squeezum feryea. roverman.

Do we have a rep or something?

Rep......well let’s say if someone wants to take a 1 of 50 Austin Healey 100s and put an LS1 V8 in it well any forum full of fuddie-duddies would stick their nose up, gasp for air and mumble insults under their breath with a demeaning closing statement and then send them over to the dark side....aka the British V8 forum. It has happened before and will happen again. It is a vicious cycle!

And Rick wonders why I haven't signed on with Namburger. No secret. Hey Art, lessee with that 2 hp per cfm figger and the 402 cubes you could make..... um....lessee...figger, figger, figger... Yep, that's it! Fourty Eight Hundred and Eighty Horsepower!!!!

Betcha that'd make yer buggy roll.

Jim

For the rekerd, Mr. Gunpowder Pantz, Increase of (1) cfm.@ 28", as measured in an "Intake Port", on gasolene per 8 cylinderz does approximate (2) hp. Mr. Vizard, can youn help me here? roverman.

Mike, I hear Ya. I got the same, "MUY CACA" from the Jensen Healy Club and the 1st gen "Celica" club about "destroying" the resale value of a $2,200 and a $400. car. I haven't solicited anyone to fund my semi-baked scheems, therfore and forthwith, I shall build any damned way I want ! These self-appointed "judges" act like it's, "THEIR" car !! I'ts enough to "Up-set The Good Humor Man", roverman.
