First off Death Valley Ca. just 100 miles down the road from here. I use ta live across river from Needles Calif. << 118 degrees in the shade. 92mm barrel,s << 1835 jhgfchrfvbg>> Suck ! They heat up cause the wall,s are too thin ? Then warp , Distort , << Causes excessive blow by wich in turn heat,s the motor oil even more , Then inturn they cause excessive head temp,s leads too droppin valves . >> same thing on the 1641 cc or 87mm barrells only not as extreme . 90.5 is what ya want 1776 motor or a 90.5bore with stroker crank . Bore times stroke = CC,s or displacement . Now far as power improvement goes with 1776 motor it,s considerable with a basically stock motor , or head,s. If ya want more be prepared too spend some money ? As i got close ta 3500.00 in my 1776 << Gas in Gas out ! Is the Key i have close too 900.00 alone just in the 043 head,s , rockers and solid shaft << Not too mention the Tri Mill ceramic coated exhaust , as i runn a Baja etc. lott,s of time in detail will give you a considerable more horse power on a long hot hard drive ? Over the bigger bore motor,s ! As im sure most of you guy,s have experienced the buggy motor that runn,s like stripped arsed ape when first started but after a hard hot cruise the engine tend,s too loose that peppyness << Mean,s it,s runnin hotter than it should ? I reccomend an engle 110 cam << This camm how ever does require solid rocker shaft,s , with new rocker,s , and dual carb,s are a must for a reasonable idle ? Now too have a rebuilder , rebuild such a motor for you isnt probably gonna happen as the time spent on a motor become,s cost prohibitive for the rebuilder ? So too have some one rebuild a 1776 motor for you is too make the builder a list of every thing you want in it or done too it << This will definately increase the price considerably ? As i laugh my ass off at advertised prices for motor,s i see in Hott VW,s and Trend,s Read small print Exchange <<< 50 percent of the core,s are not exchangeable <, This add,s considerable too the price ? As i know what it cost me ta rebuild a motor here just in machine work , and parts ? You can easily spend 100 buck,s just on barrell stud,s <<,6mm chromoly etc . if your interested in a list of basic requirement,s too successfully runn a 1776 motor ? Post again as there are many lil trick,s that both improve performance and reliabilty>>. Full Flow, 8 dowell crank , lightend fly wheel, Standard case, oil sump, Gene Berg oil pump, list goes on , and on ? Saying is when asked how much this all will cost is >> How fast ya wanna go, and how many day,s out of the week do you wanna do it ! Sean
