hello i have a 88 monte ss i took out the original 305 engine and swapped it with a 350 with mild comp cams and lifters and high volume oil pump edlebrock 600 carb, and a holley street dominator intake with the stock distributor cap rotor and the factory coil from the 305 . the car will not start at all it cranks and cranks but will not start as if the timing is off 180. but the firing order i checked over an over an its right as i read on the computer 1-8-4-3-6-5-7-2 clockwise with the copper strip on the rotor facing my number one cylinder and my number one wire on the cap is at the bottom right facing the front right side of engine. while cranking it act as if it trys starting with my dstributor cap twist more to the rear of the firewall but then i get a backfire out the carb sometimes its just gas sputtering out an sometimes its alittle flame then goes out ... can someone help me with this thanx alot
Can someone please help me with this

Well I mean you said it yourself it sounds like its 180* off because it is. You set the #1 plug on exhaust instead of compression. Pull the dizzy out, pull the number 1 plug and have someone tap the start until it spits air out the hole. Then get the timing mark to TOD and drop the dizzy in again.

do you mean your number 1 is on the passenger side of the engine?...if so it should be on the left (drivers side). The #1 cylinder is on the drivers side

When using LH or RH side, it's determined from a rear view of the car. LH=driver, RH=passenger.
X3 on being 180* out. Do what Stomis posted and it should run. If you don't have help with bumping the engine you can always turn the crank with a socket while you eyeball the balancer for TDC. Let us know what you find out.
hello to royal smart no its set to the drivers side in front of power steering bottle is where my #1 plug is .. and stomis
G Body Guru ive done that as u said already and i even pulled out the #1 plug and tapped the key until my finger blew out from in front of the hole ...then i tryed to put a screwdriver inside the hole to see if it goes in an it doesnt because the piston is blocking the #1 spark plug hole thats correct right ??? then i drop the distributor in until the copper strip on the rotor lines up with the #1 spark plug correct ?? and yes its the LH = Drivers side thanx again

If you have compression at #1, double check the that the balancer mark is at TDC. If it is then you're all set. If not, you need to bump the engine until it is.
When you re-install the distributor, the general direction to point the rotor is toward the #1 cylinder of the engine, but more importantly is that the #1 plug wire on the cap is aligned with the rotor tab.
We know you have spark because you said it back fired and flamed out. We know you have fuel too. Probably wouldn't hurt to double check your firing order too. Nevermind the 84-86 HEI label on the pic. I found this just for reference. I apologize if any of this comes across as insulting. I have no idea what level of mechanical experience you have but hope it helps.

hey thanx g body vet u guys been very helpful and no i didnt take it offensive this is actually my first time ever doing this ive bout this car a few months back and decided to do it all myself for the first time every bit of knowledge i take in and one day ill get to the point where i can help others the same as yall do ...thanx alot ill give that a try and my wiring is excactly the way it is there and same firing order ... thanx again
thats sounds like the problem I had when I was 16 and did my first cam install. I installed it way off and had the whole backfiring, flaming carb, hard starting and when it did start the motor would buck like it wanted to jump out of the motor compartment! luckily I had a gear head uncle who figured it out pretty quick it was flaming because the cam was so off that at the compression stroke the intake valve was still open, hard to figure how I didn't break anything, that was my first and finale cam install, sorry for the long nostalgia, but you should take the timing cover or valve cover would be easier off and check the relation of the valves at the compression stroke if nothing else works, I tried to mess with the timing for few days before my uncle came around and done her right, of course with alot of ribbing/teasing his young nephew and always with his "read da book" I did, still didn't work out :lol:

Your not making the same really dumb mistake I made the first time I swapped a dizzy out are you? Your pointing the rotor to number one contact on the cap not number one physically on the engine block right?
