I want to Rebuild a 99 5.7 lt(350) to fit in my 94 Chevy I want to bore the 99 motor .40 over why? is the bore damaged? why not the much more common .030 over? and can I bigger rods and a bigger cam in define bigger rods, stronger or longer (6.0"), both can be done, though the 6.0" rods will require custom pistons. you can put a bigger cam in it (but it will run like ass unless you get a custom PROM made). However the hyd. roller cam in the vortec motor isn't all that bad esp considering it puts out 45 more HP than your '94's 350. it? And is it possibe to adapt my fuel injection to the 99 motor? yes, but it requires a GMPP TBI for Vortec heads intake manifold. the biggest problem will be getting enough fuel into the engine, may need to look into a adjustable fuel pressure regulator. HTH, Bret |
isnt that big of a deal, What would you recommend for heads(I already
sold them) I was thinking longer and stronger, Will short, flat top
pistons work? with out a lot of machine work? What is a PROM? What
is a GMPP? Thanks Daniel

HTH, Bret The 99 Motor is out of a burn and is locked up but .03 or .04 bore isnt that big of a deal, What would you recommend for heads(I already sold them) heads depend on how much you have to spend, lowend being stock Vortec heads, high end being Edelbrock E-Tec 170's. but you can also get a regular ported head like a fast burn and retain your original TBI manifold (or upgrade to the Performer TBI). I would definately not get a set of TBI heads, there are just sooooo very much better heads around. I was thinking longer and stronger, Will short, flat top pistons work? you have to get pistons specifically designed for a 6.0" rod, the wrist pin hole is higher to accomodate the longer rod. what a longer rod gets you is increased piston time near TDC and lower piston acceleration rates. the advantages are you get some more power and don't have to run as much timing. the down sides are oil control can be a problem as the wristpin hole moves up into (or very near) the oil ring. 6.0" rods are readily available from Jeg's or Summit. with out a lot of machine work? What is a PROM? Programmable Read Only Memory, it is the memory module that contains the fuel maps and other engine operating parameters. What is a GMPP? Thanks Daniel General Motors Performance Parts HTH, Bret |
What type of intake manifold could I use so that I can still use my
exsiting computer and throttle body Thanks Daniel

it depends on which style head you use, if you use a standard port head, you can use either the stock TBI manifold or the Edelbrock Performer TBI manifold, I don't know of any other manifold specifically for the TBI and standard port heads. Holley makes an adapter to use the TBI unit on any spread bore or square bore manifold. if you use vortec port heads, you're limited to the GMPP TBI manifold, afaik. HTH, Bret |
Doesn't seem to know too much about motors in general. Just my $0.02.

I think the issue with the vortec heads.....and then the matching intake confuses many. Is GM the only player in town as far as a intake manifold on the vortec 350 heads.... ? It sure would be nice to run vortec heads and a performer intake with fuel injection, but as far as I know there is no such thing........... Better to ask around of those who work in the mechanic field. Now that there are a number of varriations of the chevy 350 it would make sense to verify any information by asking more than one person. Edelbrock makes an intake manifold for the application about which you speak. Runs under $200.

| I know they make an intake for the 350 TBI motor... Throttle body fuel injection and non-vortec heads Do they make an intake for fuel injection and vortec heads? Is that what you are saying...... I'll have to hunt through their catalog, I have one of the new catalgs but I've not bothered to look into it, since my 92k1500 has the non-vortec crappy heads. |

they make an intake for their pro-flo EFI for Vortec heads, they don't make a GM TBI intake for Vortec heads, AFAIK, only GMPP has one. -Bret |
