Questions about upgrading my engine

**third_shift|studios** · 12-03-2005, 08:30 AM

i'm trying to generate a long-term plan and i'm just looking at some prices. I'm thinking of putting a forged 427 in my ws.6 but i'm looking at some 402's from Tbyrne [sponser] and they seem very well priced. I have some questions though:

what's the difference between a "high compression" set up and a low compression" set up and which would be best for street and highway applications [high end power]?

Looking at this image:

i can't see the cam-shaft in that picture? doesnt' the cam go in the hole in the middle of the block? I'm asking b/c Tbryne says it comes with a cam http://www.tbyrnemotorsports.com/ls1shortblocks.html

What about the rest of the engine-like heads and valve train? any recomendations?

I'm anticipating a complete rebuild of the drive train. Clutch, tranny, drive shaft, rear-end. Prolly in about 5 years? i dunno. anyway, should I figure 5,000? 10,000? 15,000?

well the lower compression engines run super and turbo charghers on them, you know how much mins cost and i didnt go stock at all with almost anything. it was about 6 but nothing is forged in mine, i would keep the 346 unless u plan on keeping the current car you have or gettinh another one cause a 402 or 408 or even a 427 is going to be massive amounts of power and i mean a shit load of power man. with the 427 were talking like over 600hp. my advice is take $50 a paycheck and keep it in a seperate account and then you will at least have some money to play with when your ready.

casue my engine alone cost me 6k!!!

i wanna bigger CID b/c i don't want to put power adders on. infact, i have set up a "car account" in my bank where $50 a month goes into a savings. I would do more, but i'm doing the same for the wedding...

Well....if you are an engine builder and are fairly good with cam geometry..head flow/viscosity...piston plane etc. then you can build an engine this way...part by part.....or pay a good engine builder ( no not a mechanic and engine builder) or get a crate engine ready to go with a warranty....

That's a bad bad boy for $5600...
Bolt that bad boy in and go kill Zboner

to bad he is not an engine builder

, and by the time he has money to buy this i plan on having heads and forged everything oh and a 300 shot so he will be

by me still

TTT...c'mon guys i need some more input here

If you are not interested in power adders than you will want a higher compression engine. I believe if you are to use a stroker kit they are generally higher compression than a stock set-up. However that it something individual to your heads, and pistons. What kind of valvetrain and top end are you planning on building? This will help us with your set-up.

i don't have a clue about valve trains or heads. i'm not a gear head-i just wanna make it fast.

My iron block 402 build is costing me about $12K.
Of course, there is suspension parts included as well. But I didn't get the heads I wanted. Would have been another $1200 for those.

My shortblock cost me $3730 from Texas Speed. LQ9 402. Lunati Pro Mod rods, Eagle crank, Mahle pistons.
Compression is determined by what the pistons are. Dished or flat-top with a stock cc head. Dished will be lower compression, better suited for boost. Flat-top (or a low cc dish) is better for higher compression, better for N/A or nitrous apps.
