Thread: Tunnel ram intakes

Tweet

Soon ill be looking to start building a tunnel ram motor for a buddy for his 33 gasser...

hes got a 350 sbc 1988 motor, but cannot seem to find any intakes listed for this age motor....

they all seem to stop on 86 ?

has anyone tried them and if they fit ?

regards

Depends on what heads are on the car, Mike.....

Dave,

There the Stock cast iron heads

Hmmmm. Better wait for the sbc guys.... Not sure if you have the Vortec heads on that vintage or what, I'm a Ford guy. Just thought I could maybe get some responses going here to get you some accurate information.... Think I know the answer, but not sure and I don't want to be guilty of giving you incorrect info!!!!!!

i could get the casting number off the head

the block cast number is 14093638 dates the block 87-95

it had 2 barrel TBI on it

if the heads have only 4 bolts a side then it is Vtech head. if has more then 4 per head like 6 on each side then a older intake is a bolt on .but the middle bolts are at a diffrent angle so you have to check if there room to open up them holes and make stand offs so they can be TQ up. if a Vtech head the ports are abit taller but the tunnle ram should seal up you would need to check that you could drill and tap the V tech and use a older intakes they did not come out with the Vtech heads in the late 90s? 1999 may have been the first year ? i know the 2000s where i have built some pricy to build

Thats cool

there's 6 on each side according to mortec site cast number 14102183 reads this
14101083...87-up...350..........Gen.I, also used on crate motors, 285 or 300 hp, 64c chambers, 72' center manifold bolt angles..

does that mean the heads should fit the intake ?

the intake if older the middle bolts will be at all the same angle so if newer heads you will need to fix the intake if there room to work

Thanks Pat, thought that's how it went but thought I'd just pass til someone came along that knew for sure!!!!!

There ya go Mike! Pat's a machinist and motor builder for a living, got the straight skinny now!!!!!

Thats Brilliant guys

Have to keep a look out now for a intake

best regards

Mike I wouldnt exclude the earlier ones availble. "hoggingging out" the holes is pretty common, but like said earlier , its a matter of having enough meat to do so.
