Road Agent

Don't for get the air foil!

emo-vet

how ya going road agent,
what a air foil for each of the 8 seperate throttle bodies i have you mean ???
i didnt know they made them for 8 x sepearte throttle body intakes,lol

Jonnymac

When does the LT1 version come out.

cv67

You are better off with a stock weight crank for the street, anyway. Lightening the rest is good IMO.

You could get by with some 195 Comp Elims, too if you wanted.

I thought Low tension oil rings were bad.....

emo-vet

hi there guys,
thanks for your replies.
yeah i was thinking about going 195 afr heads ,but bosch vette reackons the way the 8 t/b intake breathes as in breathers very well, might as well go larger heads for that extra breathing capacity.
r.e low tension oil rings, yeah i heard some thing along those lines as well,but i have had a few reputable guys not say any thing bad about them so i left them as they were i guess.
try and see.
but thre light parts should work real nice and rev like theres no tomorrow.
but i would think i should at least gain 450 rear wheel or more plus horsepower for sure would be real nice.
infact some guys reackon i will sh*it my pants with this set up.
cant wait to se that happening,lol.
r.e the lt1 version come out well they make these 8 t/b intakes for all types of chev motors actually guys.
any way cheers for your replies.
regards
shae

I would't have gone with .060 over bore if I could avoid it. .030 leaves stronger cylinder walls, and allows for a rebuild later on. Other than that, It sounds like you've got some good parts to work with. Luck to you on your project.

emo-vet

hi curveit,
how are ya!
yeah i would of liked to only have to only bore block out to .030 " myself ,but the 4 " standard bores in this second hand block were fairly worn and will have to be taken out .060 " that is .30 " each side of bore that is to clean up very nice.
the main problem is there was a wear lip made at the top of each bore unfortunelty.
but on these blocks they can take .060 " ok and still be alright.
especially running full synthetic oil and high flow electric water pump there to keep things running cool.
but yeah then this will be the last time of boring for this block and then i will have to convert my 2 bolt roller block in to 4 bolt main splayed caps engine for my next engine.
buy yep im pretty happy with the list of parts i have chosen and brought.
cheers mate

"and they are doing the engine internal balance rotating for me."

Is the flywheel neutral balance?

Iroc57

You got lots o' stuff there

Enjoy the build

staugur

Shae don't forget you can always sleeve them and probably cheaper than a whole new rebuild.

steven mack

You are going to regret those low tension oil rings.Chevy used them in some later model vettes and had alot of oil consumption problems.

Pete K

The late model, 1 pcs seal blocks are garbage, compared to pre 80 blocks. Most are too thin @ .030. Going to .060 without a sonic test is a 50/50 shot at failure.
Low tension rings on a street motor is an almost 100% problematic.
Sounds like your mind is made up. Hopefully the dice roll in your favor.

emo-vet

hi guys,
how are ya!
ok im listening to what you are saying and i will exchange low tension oil rings for some thing else as parts havent been sent of yet thanks pete k,next i found out that flywheel is neutral balanced thanks rod and i will get block sonic tested before i go ahead with the block!

so r.e sonic testing, do you get this tested after the bores are bored and honed or before work is stared please ???

can any one please reccomend any race quality plasma moly rings set then please for me to buy ??
cheers
shae

Matt Cramer

I can't wait to see a dyno graph of this.

emo-vet

i know,im looking so forward to hearing,driving,seeing dyno results as well mate.
so any rough idea on what this motor might produce/put out in rear wheel horsepower guys please ???
450 rwhp is a rough guess and thats what boschvettes 8 t/b intake 11:1.0 comp motor puts out at rear wheels.
cheers
shae

emo-vet

hi guys,
i need some quick help please now on your new advise given on not to buy" ultra low tension " piston rings as they are no good.
so do i buy then please?
they need top be good quality race rings please.
here is a couple of brand names in quality,
total seal
hastings
mahle
perfect circle

then there is diffrent types in standard tension
gapless rings = i heard can break easily when filing down on piston and just a pain in the *** !!
high tension
and ultra low tension rings = no good,too much oil consumption.
remember that i need them to be 4.060 " bore size please with gap size to suit pistons of 1.2,1.5,3.0 mm.
any ideas or help,links please ??
thanks
shae

emo-vet

well,can any one please advise me on what rings to now get please then ???
thanks
shae

Pete K

All of the brands you list make quality piston rings. I am a Hastings fan, but only because I have used them without issues many dozens of times.

Standard tension, moly rings are all you need. Here in the us, they are a $40 ring set.

What does your engine builder prefer? His opinion is the most important.
When I am building one, and the customer brings me a printout of internet recommended parts, I usually show him the door. Be sure the builder is on the same page as you.
