Well, i'm not asking what i should do, because i have already done everything but i wanted some feedback on my combo. It started as just taking the engine out of my 88 'bird to swap on some 305 torquer heads from World, however upon removing the heads, i decided to go ahead and rebuild the engine. My parts list is as follows: Silvolite .30 over pistons, hastings rings, stock crank turned .10/.10, stock rods with arp bolts, clevite 77 bearings, melling HV oilpump, canton roadrace oil pan (6qt), edelbrock tbi manifold, stock tbi, stock injectors, MSD billet distributor, superconductor wires, dynomax headers (emissions legal), Comp cams pro mag roller rockers (1.52), comp cams hydraulic roller lifters, Comp pushrods, Edelbrock waterpump, Edelbrock timing set, Comp xr258hr roller cam (.480 in/ .488 exh 112 sep). Arp head and main bolts. I am in the stages of finally assembling it, i plan on blueprinting the engine, and i had the machine shop do a complete balance on it (w/in .5 gram). Any suggestions or things i may have missed? And yes i am sticking with the 305.

Thanks,
Mike

since you are spending all that money, have you ever concidered going to a 350? personaly i think it would be a better route.

if not the buildup sounds pretty good. the xr258 is a descent cam for a 305, the xr264hr would also work. the 264 is really going to shine, if you ditch that edelbrock TBI crap, and get a good 4bbl, i think with the bigger cam, and aftermarket heads, you are really going to be wanting something that flows the kind of air you want, you might look into the wieand 7525, it is a single plane, and still has EGR. also, the stock throttle body is just not going to cut it, for either your buildup, or one with the parts i listed. you are going to want to get a 454 unit, or holley 670. also , hope you like the idea of getting into tuning, cause your goona need computer work no matter how you cut it.

Dewey Nailed it. You will have nightmares if you do not get it tuned. He is also right about the stock TBI and injectors not going to cut it. You may need a new fuel pump as well even if your old one is working fine. You will need a solid 15psi at WOT and the stock one won't cut it. You need to feed that beast.

Thanks for the input, what kind of fuel pump would you guys recommend? Also, even though i know it may not be directly related to tbi, what equipment would i need to get into chips? I was figuring on probably replacing the tbi, the holley 670 would do it? I was looking at getting my piston tops possibly coated, if not my chambers too. Would this be any type of noticeable difference? Really appreciate your help.

i would get a walbro 255lpr.

to get into chips you will need a chip burner, i use the pocket programer 2, check the DIY board for more info on burners.

you will also need a program to modify the data, i use a free on called gmecm, again, check the DIY board. you can also purchase tunercat, which is a VERY nice program, but not free.

you then need some way to gather the data, for this get winaldl (free) and build your own cable (cerca $8 for the parts at radio shack)

since moates isn't selling his TBI adaptor anymore, you will need chips, and a UV earaser also.

then the only other thing you need is time. and lots of it.

Is that the 60psi pump? I saw one on ebay for the 198 cars, i assume that is the one i want? I want to use the weiand but i need to pass the ca smog, since it is a visual as well as a functional, i guess i will just stick with the edelbrock tbi, since it does not require the use of a spacer. Has anyone had any experience with the 7525 in CA relating to smog? IF i absolutely had to i would probably be able to swap intakes every 2 years, but i would rather not do that.

THanks again,
mike

Also, if i get into prom burning, would i need to swap computers? I have been told that teh 88 computer is sort of an oddball? Also, what would that involve if i did need to swap computers what would be the best donor? THanks,

Mike

they make both the 60psi version, and a lower pressure version, i am not sure if the regulator can regulate down from the high perssure version or not.

88 is an oddball year, not sure about the tuning of it, as i don't have one if you were to swap you could go to either a 8746 from an 89+ or to a 747 from the trucks, either should work.

not sure about the wieand and CA smog ****'s. it does have EGR provisions, but whether or not that is enough in california is a diffrent story.

definitly ditch edel. tbi intake. go with a 4bbl,however ive heard you need mathed injecters for a 4bbl intake-dont really know. but your combo sounds exxxcelent.:rockon:

well, does anyone from ca have experience with the team g? Most of the time i think we need a CARB sticker which is probably hard to get unless it comes with one from weiand. Also since it is a firebird, i wonder if i would have hood clearance issues with the adapter and the manifold? Thanks again for all the info, one more question, is the holley tbi adjustable pressure? or will i need to get an adjustable regulator also? Thanks a lot guys.

Mike

When I built my engine, I talked to MANY differant engine builders on oil pumps, no I don't know if this is true but they all said that a HV oil pump is a waist of time unless your turning 7000 rpm, they also said it robs quite a bit of power. Is this true?

Sounds sweet dude, ima get a 305 block from this kid and rebuild it bigtime. Nice to see more people rebuilding there 305's

SSBO

i was told by my builder that since i was going to the 6 quart roadrace pan, i would probably need it. Originally on the stock pan, he said no outright, so i trust his opinion. This pump is high volume, not the high volume high pressure pump which i understand they also sell. Thanks for the info though.

Mike

Sounds like an alright combo, just need to get the tuning down. I just question why you would rebuild a 305?

Are you actually talking about wanting to rebuild a 305 for performance???

I already have a 350 in a 70 malibu, so i wasn't real concerned about this being the "fast" car, i am building this one primarily for autocrossing, which i would like to get into. Suspension mods are on the way. I just wanted a solid combo and felt like rebuilding the 305.

Thanks for everyone's input,

Mike

That makes sense, and I understand that. But for somebody to go pick up a 305 block to rebuild is kinda insane IMO. There are more 350 blocks out there - and many of em are virgins. Why not start with one of those?
