Hey you guys, its been awhile since my last post...I have since found out that what i thought was a 350 was indeed a 305, so where im at right now is that i have my 305 being taken apart day by day, what im here to ask is will my project work with what i have without me having to get more parts. here is what i got, carbed 305 out of a 1986 Camaro, 84k miles on the motor, New main,rod, and cam bearings, New CSB complete gasket set, .292/.292/.488/.488 i believe are the numbers on my new cam. I have a turbo 350 tranny to put behind it, i just want to know if that will work or would it bomb? also i was told my car came with 411 gears because it came with a v6, to make up for power, is this true? I have a 1988 firebird that came with a 2.8Lv6, please let me know, Thanks

 

the 305 will bolt to the th350 if it has a 9" tailshaft stock driveshaft should work dont know about the gears other than pulling cover and counting teeth on ring and pinion gear

 

thanks, my main concern is the cam, i was told it would be a pretty rowdy cam for a 350, i wanna make sure i can run it in my 305 while still running stock internals, i also forgot to add i have gm performance heads aswell.

 

You dont have nearly enough stats on that cam to know anything about it. Assuming it's .488 lift on the intake and exhaust side that puts it in fairly tame company for street car cams, the problem is if that's all the numbers you got for it, it's probably an old school grind that's not all that good at giving you a nice usable wide powerband like the newer cams do.

 

Sorry about that, I went through and found the cam I bought.

Way too much cam for a 305.
All the '85-up v6 cars built with automatic also got 3.42:1 gears. The T5 V6 cars got different rear gears in different years. In '85, it was also 3.42:1, because the '85 V6 t5 had a 3.50:1 first gear. But for '88, the V6 T5 got a 4.03:1 first gear, so the axle dropped to 3.08:1.
If you're gonna put a Summit cam in the 305, limit yourself to the 1102, which is 420/442 lift. You'll hate it if you go any bigger.

 

thanks, unfortunately money is tight and i have to use what i have, will the 305 be able to withstand the 1106?

 

Probably NOT. Probably 2 reasons. One is the springs, the other is the retainer-to-guide clearance. Changing the cam is the cheapest solution. Or use the 305's stock cam.

 

I have gm fast burn heads off of a 350, would that make a difference?

 

Wow, the mismatch continues.

A $55 cam would be cheap insurance against frustration. But, those Fast Burn heads wouldn't work well on a 305 without making the whole thing pretty much unstreetable.

 

Well, I have a daily driver already, if its almost unstreetable I wouldn't have a problem with that lol

 

The list of crap parts you already bought, it defies all reason. You start with a lame old cam, and now you add the second worst non-production SBC heads ever conceived. Those heads don't even flow as well as the iron Vortec 350 truck heads, despite larger intake valves, (which won't clear a 305's tiny bores) and another 40 cc of intake port volume. That's why they're crap.
Look, sell them, and the stupid cam, and buy some sensible parts.
If it seems like we're ganging up on you, then that should help convince you of your error. We're here to help. five7kid can't type some of the things I do, because he's a moderator, but the message is the same.

 

What I was thinking.

 

I was asking for some simple answers, Im appreciative, I really am, but i feel some of the things you said were rather rude, I guess either way I got my answer.

 

What part would you consider sensible then? I have low funding and want to add a few things to make the motor pretty wild

 

Low funding, pretty wild and 305 don't make a very good combo. You will get many opinions about how to buid it and how to spend your money.

If you are using a carbed set up I say get good vortec heads, a moderate (for a 305) cam...212 to 220 split profile duration @ .050...maybe some 1.6 rockers, a highrise (Edelbrock RPM) type manifold and a good Q-Jet carb. With good exhaust components this engine will make decent power. This combo can work with or without electronics. Add gears and it will roll out nicely.

FI is a different animal I wil let someone else explain.

You can sell the parts you have and buy used items to complete the job....or rob a convience store!

 

I thank you, that really helped, I don't plan on doing FI anytime soon, I'm not even sure the heads I got are fast burns, that's what I was told, I'm gonna try and post a pic up here so you guys can tell me if that's really what they are, I might just get a junk yard 350 for back up, because its what I would rather have anyway
