67Polara

what do you guys thinkabout putting a blower on a 67 Polara ?

I want one on my 53 Plymouth sled...lol....on the inline 6 cylinder.

thad be pretty cool, i'm just having that issue of do i want to keep it stock n classy or go all out on the car.

you have to be sure that your engine can take it

67Polara

how would i go about doing that ?

67 GTX

your compression can't be too high
you'd need stronger rods, crank, etc.

With a blower you want to run ~12:1 I heard. Your lower end has a to be beefed up to handle the force along with the valvetrain. Its a lot more work than most people think. What size blower are you looking at?

67Polara

i'm not sure what size i dont know to much about cars mechanicly

We recommend 8-8.5:1. Some combos can go a bit higher, but some will require intercooling to prevent detonation. Many variables go into determining a combo. What are your goals? I mean are you looking at putting one on for a certain amount of horsepower? Just want one mostly for looks (we get that more often than you would think), or maybe just like the way they sound? I find that if I understand what someone is looking for, we can point them in the right direction a little easier.

What is a higher compression ratio needed for then? I thought it was for blowers.

theomahamoparguy

no, just the opposite. More boost-more pressure so you start with low compression. 12:1 compression would blow the heads off the block!
I like the idea of twin turbos. Plenty of room under the hood of that C-body for it.

how would i go about finding out the compression on my car ?

SMRE

You might be thinking of NOS or something else. You don't need the compression for a blower for sure. You can get away with a little more than 8.5:1 in many cases. It really depends on a number of factors.

67 GTX

you always want lower compression with a blower
if not, you'll literally melt the pistons

67Polara

ok i think i'll just fab a hood scoop then lol

67 GTX

a compression test should do it

67Polara

well if it wasnt right i wouldnt kno where to go from there n i dont want to take the chance of messing up the car, i need it every day she's my daily driver so, but more importantly i dont want to hurt the car in any way.

67 GTX

good choice
since its your DD, dont do anything radical to it yet

67Polara

yeah i think that would be a wise choice there, thanks =)

67 GTX

no problem

LOLi thought about TT my 383... i think im just going to go with some new heads intake new carb and cams for now..... then this winter mabye new crank rods pistons...imma play it off as "Hey babe, i need to paint the engine block...and in order to do this....i need to take it apart" and alas ILL forget where i laid CERTian goodies...and need...newer ones LOL

but in reality TT and SC been on my mind, but i dont know what the 727 is ca[pable of handling as its an automatic This will be my first AUTOMATIC car im tackling and older car at that so im a little dumb about autos....

i just had the tranny rebuilt though,So i dont know if TT or ST or SC is an option? id be doing all the grunt work if its turbo i go with, im not looking for nothing crazy just something different,Thats if these trannys are capable of handling this?"
