I got a lo5 reman. roller long block for $1000 and changed the heads out with some reman. #113 allum. D-port heads I bought for $400. Tryin to decide on a cam. I Siamesed my TPI intake approx. 2.5 to 3" Ive heard you can lose your lowend torque doing this. The car will mainly be street driven with an occasional trip to the track. I really like the the specs on the Ramjet cam and can get a new one cheap. Is this a good choice for my heads and to retain some low end torque? With my 1.6 rockers the max lift will be like .481. I know the 109 lsa will be hard too tune also which shouldn't be a problem for me. Or should a go with a different cam? Thanks for all your replies.
