yeah 86 blocks should have the bosses for the spider, like mike said drill and tap them.

Epic tpi build info in here.

today a guy at work pulled his intake on his lt1 roadmaster cuz it was leakin so i got to take a look in his valley...no his had three bolts holding the 'spider' down and it was elevated by maybe like 3/8" my motor only has two places and they are not elevated. but the height could always be made up with a spacer but would two bolts be sufficient to hold it down..they are pretty close together...

nope your block doesnt have the right valley. Sorry buddy! But you can buy Retro Lifters.

Is that motor a lb9

yea its a LB9

i feel like it would be a lot easier to just get a cam with similar specs to a lt1 that is made for my block lol

possibly something like this.... http://www.jegs.com/i/Lunati/638/60100LK/10002/-1

id hate to see you put a cam in it first off spending the doe and Not getting what you really want from it! i say get what you KNOW will work on a stock tune. or spend your money were it really needs to be and get a real ECM for it. it will work for your car and i have a 1993 LT1 computer harness. its a FAR better PCM then the Tpi one you have and you will go speed density. and i have the tuning software to fuck with it wen you get a chip burner. or better yet save up piece by piece and get the 24x setup. either way your gunna be dissapointed and Very limited on the 86 PCM. sorry had a brain fart and felt like a rant was in order!!! SO FUCK YOU! hahaha

^thanks real helpful. ahahaha

fuck it. im just going to put it back together for now. i got enough other stuff i got to dump money into. ill just port the base and do runners and call it good.

get a stock 85 305 tpi cam or a stock 85 350tpi vette cam. both are flat tappet and larger than what you got.
