Guest nosz350 Posted June 10, 2001 Share Posted June 10, 2001 Does anybody now anything on this small block combo? Bowtie block,big crank, long rod something like that, I can get a deal on it,$4400.00 short block, PRO 1 heads ready to go $1200.00. He told me 600-750hp does that sound right?

Guest Anonymous Posted June 10, 2001 Share Posted June 10, 2001 Sounds like if it puts out that sort of HP that it'll have one doozie of a cam in it and be marginally (or not at all)streetable , also whats the compression ratio? Here is speedomotive's 434 kit. I guess it depends on what your doing with the car? Strip only? http://www.speedomotive.com/newpage3.htm Regards, Lone Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted June 10, 2001 Share Posted June 10, 2001 The site Lone gave for the 434 kit offers the engine w/4" stroke...this means a bore of 4.155 is required to obtain 433.89 cu in. All SBC blocks have a Block Deck Height of 9.025; deduct the 6" rod & the 1/2Stroke of 4" (this equals 2") then you only have 1.025" for a piston comp.height; they list the use of a JE piston w/dome but doesnt say how large the dome is. Chances are their machine shop has removed .010 from the block deck height just to square the block-so its possible the piston comp.height may even be less than 1.025"....the only way to know for sure is to call them & inquire. They do give the 76cc combustion chamber a 11.6:1 comp.ratio. If durability is in mind/you may want to rethink your choice as their advertisement does read "Racing Engines"...not Street/Grocery Getters! Now-as Lone mentions if a race only engine is what you're looking for...go for it; just remember-the closer you get to the exotic displacements the more maintenance is required & sometimes this means a daily/weekly/monthly rebuilding of said engine-depending on how exotic you get. I'm sure if you wanted a streetable 434 you could use a 5.703 rod & this would leave a more reliable piston comp.height of 1.320 w/.002" to sqaure up the block if it were needed & maybe a flat top piston to lower comp.ratio & a milder cam...but then you're back to a mere performing SBC & might as well go 383, 406, 408(?)...something to think about. Then again there's nothing wrong w/a 9.5:1 or 10.0:1 comp.ration 434 stroker!!! Its all about what you personally want-so weigh your options & then make an educated decision...then dont worry-& be happy! Kevin, (Yea,Still an Inliner) PS: I like that site Lone gave-their "Engine Building Tips" is a book unto itself...I always appreciate an engine building business/shop that isnt afraid of edjucating their customers by divulging trade secrets.
